Single channel fluorescence was detected by using phase sensitive detection in our experiments. A coupling laser power dependent study of the EIT feature was carried out. Our findings have been complemented by theoretical studies of open systems that trace the presence of EIT starting from the density matrix equations. Numerical simulations have been performed and are in excellent agreement with the experimental results. Polarization Rotation and Circular Dichroism Near the Potassium D2 Lines Charles Conover, Htet Thiha, Jennifer Dahnke We have experimentally measured the Faraday rotation and the differential absorption of the two circular polarizations for light tuned near the D2 line in potassium In particular we have explored the vapor temperature and magnetic field dependence of the frequency of the zero crossings of the lineshapes from the circular analyzer and the balanced polarimeter used in the measurements.
These signals are routinely used as frequency references for laser locking and we discuss the sensitivity to experimental parameters. However modern microresonators are often so small that corrections to the planar approximation become necessary. Interface curvature is accounted for by only modifying the wavefunction describing propagation in the less optically dense medium.
The theory is applied to dielectric cavities and our results compared to those of an independent calculation obtained from a sequential-reflection model . The advantages and limitations of our alternative approach will be discussed at the conference. Preserving near-field uniformity while inducing far-field directionality G.
A major issue in the latter applications is the difficulty to obtain directional emission of light in the far-field while keeping high energy densities inside the cavity i. Interestingly, the transition between a uniform near- and far-field to a uniform near- and directional far-field is rather abrupt.
We can explain this behaviour quite nicely with a simple model, supported by full numerical calculations, and we predict that the effect will also be found in a large class of eigenmodes of the cavity. Controlling the far field J. Using a 2D annular cavity, we present a procedure capable to achieve these two apparently conflicting goals.UKG: Atom-Pia, newest Kapamilya love team?
With the correspondence between the classical and the wave picture, properties of the classical phase space shed some light on the characteristics of the wave dynamics. Strong interactions between few-photon pulses require a combination of large optical nonlinearity, long interaction time, low photon loss, and tight confinement of the light beams. Here, we present an approach to overcome these issues that makes use of an optically dense medium containing a few hundred cold atoms trapped inside the hollow core of a photonic crystal fiber.
In this poster we describe the experimental improvements to load, probe and manipulate cold atoms inside the hollow core of the fiber. We also discuss recent experiments regarding nonlinear optical interactions at extremely low-light levels.
Especially, the use of EIT and slow-light opens the way to few-photon efficient all-optical switching.

Recoil-induced Resonances as All-optical Switches F. Although this technique has been demonstrated to be useful for the purpose of extracting the cloud temperature , our aim was to demonstrate an all optical switch based on recoil-induced resonances. We compare and contrast the switching dynamics of these two resonances and demonstrate optical switching using both resonances. Finally, we consider the applicability of the narrow, free-space resonance to the slowing of a weak probe field.

25 Questions With Atom Araullo
Sauer Spin-damping is a technique to feedback part of the optical signal from an atomic magnetometer to orthogonal electromagnetic coils in order to damp out any unwanted signal. Using this technique, the optically pumped magnetometer can quickly be prepared to detect the RF signal of interest, for instance the femtoTesla signal emitted from an explosive during nuclear quadrupole resonance detection.
In our K magnetometer, a linearly polarized probe beam measures, through Faraday rotation, the transverse K magnetization induced by the RF signal. In our study of spin-damping, we found a surprising result -- the spin-damping suppresses not only the transients in the K atoms, but also the photon shot noise.
Depending on the gain and phase in the negative feedback loop, we measure noise suppression levels up to an order of magnitude below photon shot noise. This sub-shot noise level demonstrates the correlation between the photons in the light and the K atoms in the atomic cell.
While the current demonstration is in a closed loop, we will discuss the possibilities of creating an open-loop generation of a sub-shot noise beam. Dynamics of a photon in a positive energy space is explained here with an example of a photon propagating through multiple mediums of different density.
When a photon goes through from air to glass the speed of photon decreases and when it exits from glass it resumes the original speed. This process of propagation is explained with the concept of positive energy space.
In a double slit experiment, stream of photons passing through the slits create interference patterns. A double slit experiment with single electron at a time also creates interference patterns even though there are no second electrons to Interfere. A double slit experiment is modeled here with the dynamics of the positive energy space. The model contains two components. One is the interference by phase relationship and the second is the interference by positive energy space distribution. The single electron interference is, in the model, from the second component, positive energy space distribution.
The streaming photons create patterns from both the phase relations and the positive energy space distribution. An experiment result with laser is presented that demonstrates the two components of double slit experiment. Demonstrated also is the interference pattern being created by adjacent beams traveling with different wave phase. The calculations for the positive energy space distribution of the double slits are also presented.
The output pulse was detected by a streak camera with 2 pico-second resolution. The experiment data showed the original pulse separates to a main pulse and a precursor which travels faster than the main pulse.
This gives some experiment evidence of the formation of precursor when a step-function-shape electromagnetic pulse travels through a Lorentz absorber, which was proposed by Dr. Brillouin about years ago. Viewed in the frequency domain, our methods stem from the idea of Coherently Controlled Adiabatic Passage , in which several adiabatic passage pathways coherently add up to provide the desired population transfer. Viewed in the time domain, the methods work by piecewise accumulation of the wavefunction in the target wave packet, applying the Piecewise Adiabatic Passage technique  in the multi-state regime.

The presentation will discuss the basic concepts behind the technique as well as recent theoretical and experimental developments [3,4]. A 79, A 80, Hicks, Chakree Tanjaroon, Susan D. The laser pulses were approximately 12 ps long and were near-Fourier-transform-limited. The dependence of the peak efficiency position is presented as a function of the sodium temperature, laser pulse energy, and the buffer gas that was used.
Resonant dispersive waves generated with multi-input femtosecond pulses Kai Wang, Jiahui Peng, Alexei Sokolov We investigated the resonant dispersive waves generated by high- order dispersion theoretically.

We considered two femtosecond pulses propagating in the kagome-lattice hollow-core photonics crystal fibers with different wavelength and time delay. With a phase difference, besides the two resonant dispersive waves produced by the third and fourth order dispersion, the other resonant dispersive wave in the visible range is generated in numerical calculation.
Using two input femtosecond pulse might be applied to produce the ultrashort pulse. Non-adiabatic effects induced by the coupling between Raman modes Vishesha Patel, Svetlana Malinovskaya We study the effects of coupling between the vibrational modes on population dynamics upon application of femtosecond chirped laser pulses.
In our model, the ground states of the two coupled TLSs are nondegenerate and the relative phase between them is zero. Chirp of the pump and Stokes pulse is same in the magnitude and opposite in the sign for the whole pulse duration. However, the population for the uncoupled TLSs shows population inversion under the same conditions. Dressed state analysis is performed to help in understanding and interpretation of the results. Methane, CH4 We may all be familiar with drawing methane using electron dot diagrams, which would look something like this: Covalent bonding in Methane Misconception: These diagrams are drawn for simplicity and should not be viewed as an exact representation of what a molecule looks like.
For now, let us ignore the Hydrogen and concentrate on the central Carbon atom. We know that it is the valence electrons that are responsible for covalent bonding and we must know the electron configuration of an element from the periodic table to know how many valence electron it has. Please click here to learn more about Electron Configuration if you are unfamiliar with the concept.
Now, when we look at the carbon atom from our Methane, we see that its electron configuration is 1s2 2s2 2p2. However, from this electron configuration we can see that carbon has only two unpaired electrons 2p2 in its valence shell which can be used to form bonds with two hydrogen atoms. You can see this more clearly in the electrons-in-boxes notation below.
Well the answer to this lies in something know as hybridization. Please click here to learn more about hybridization if you are unfamiliar with the concept. Forming the bonds Now that we have hybridized the s and p orbitals of carbon to form four identical sp3 hybrid orbitals, it is time to bring in the Hydrogens that we ignored earlier.
It is easy to see that the the four Hydrogens that will bond with the carbon all have a single 1s orbital with a single unpaired electron in each.

This makes it very easy for it to bond with the carbon. Sigma bonding in Methane. The two types of orbitals overlap in an end-to-end manner and form four single bonds which are referred to as sigma bonds giving us our methane molecule.
Now remember the energy that the carbon atom gained to promote one of its electrons from the 2s to the 2pz orbital during hybridisation? Well once the carbon bonds with the hydrogens to form the CH4 molecule, it loses far more energy compared to this gain which eventually makes the molecule very stable and this is what is would look like: First we isolate the two Carbons and get their electron configuration which is 1s2 2s2 2p2 Since the electron configuration shows only two unpaired electrons available for bonding and we know that each carbon can form four bonds 3 bonds with hydrogen and 1 with the other carbon in this caseit is obvious that hybridization is needed to make four unpaired electrons available for this bonding.
