... to suppression of the absorption of rescattered light in the MOT. The second-hand absorption of photons that have already been spontaneously scattered by MOT atoms, or “radiation trapping,” leads to temperature and density limitations in free-space MOTs [Sesko91; Ellinger94]. These rescattering even ...

High speed silicon based optical modulators based on carrier
... wherep is the experimental wavelength difference between two successive resonance peaks. The experimental set-up used a tuneable laser in the 1550 nm range. A linearly polarized light beam was coupled into the waveguide using a polarization maintaining lensed fiber. The output light was collected ...

... electric field they experience is zero; therefore electric field perturbations are small. Magnetic field perturbations to internal structure are important; however, the coherence time for superposition states of two internal levels can be very long by operating at fields where the energy separation ...

Construction and Validation of a White Light Interferometer
... When light from a source is split into two beams, then the inherent variation in the two beams are generally correlated, and the beams are said to be completely or partially coherent depending on the existing correlation. In light beams from two independent sources, the phase functions are usually u ...

Metal-optic and Plasmonic Semiconductor
... Over the past few decades, semiconductor lasers have relentlessly followed the path towards miniaturization. Smaller lasers are more energy efficient, are cheaper to make, and open up new applications in sensing and displays, among many other things. Yet, up until recently, there was a fundamental p ...
