Engineered photonic crystals for spontaneous Raman laser cooling in silicon
Abstract
The purpose of this short effort is to determine if Raman cooling is feasible in intrinsic silicon. An analyzer, optics and spectrometer will be purchased to facilitate the study of Raman processes in intrinsic silicon. Silicon-based photonic crystals will be fabricated to modify the optical density of states, thus tuning the relative intensities of Stokes and anti-Stokes Raman processes. A custom spectrometer will be built to observe the absorption of incident laser light and quantify the Stokes and anti-Stokes Raman processes to determine if cooling is possible.
