Nanoemitters with Efficient Anti-Stokes Emission for Self-Cooled Optical Data Links
Abstract
This project involves 3 undergraduate students and 1 graduate student, all from underrepresented minority populations, in a basic research effort aiming at development of an energy-efficient cryogenic optical data link. The ultimate concept is based on a directly modulated semiconductor laser source with very high modulation bandwidth. Waste heat generation is a generic problem in all laser systems. Reduction of thermal load is especially important in cryogenic laser applications. In our concept of a self-cooled semiconductor laser, the cooling effect is achieved through efficient anti-Stokes spontaneous emission from nanosize emitters embedded into the waveguide core of the laser structure and excited by the intrinsic laser emission. This concept requires nanoemitters with very efficient anti-Stokes fluorescence when excited at the laser emission wavelength. Research under this project focuses on optimization of nanoemitters for efficient heat removal via anti-Stokes emission at cryogenic temperatures, suitable for heterogeneous integration with III-V epitaxial laser structures.
