An ongoing large research project is the cooling of solids using laser light. I made some spectroscopic measurements of fluorescence upconversion of CdS quantum dots dispersed in PMMA. I have also recently reviewed the prospects for laser cooling of semiconductors.
A small project is theory and experiments related to eddy-current braking of tumbling CubeSat satellites. I have worked with Asst. Prof. Jin Kang and CDR Bob Bruninga in Aerospace Engineering. Two midshipmen have been involved.
I am investigating SBS (Stimulated Brillouin Scattering) theoretically and experimentally for high-power fiber lasers. I summarize chapter 9 of Agrawal's book on Nonlinear Fiber Optics. I also review computations from Boyd's book Nonlinear Optics on Brillouin amplification.
I have been interested in organic light-emitting diodes (OLEDs). I have written a review of luminescence quantum efficiency measurements and a brief note about luminance cameras. You might also tease yourself with the following optics quiz.
Additionally, I have investigated how rough surfaces scatter light into various directions and polarization states. I have written a long review of the literature on this topic, as well as a description of some measurements I have performed on lidar targets and building materials.
I have also done projects on energy transfer between solid-state impurities and on photoconductivity of thin films.
These involve students and colleagues at the Laboratory for Physical Sciences, Naval Surface Warfare Center, Army Research Lab, Naval Research Lab, the University of West Florida, Los Alamos National Lab, Eglin Air Force Base, and the University of Georgia.
