Abstract:

All project goals have been achieved I. Quantum cascade lasers QCLs for lambda 4.5 micron operation have been designed, grown, fabricated, and tested. II. Fabricated QCLs were epi-transferred to the silicon-on-sapphire SOS platform using approximately 250-nm-thick SU-8 adhesive layer. QCL-on-SOS devices were fabricated and tested. QCL-to-SOS mode coupler based on tapered waveguide was designed. III. Mode-coupled QCL on SOS were fabricated. Room-temperature operation of QCL-on-SOS was successfully demonstrated. Mid-IR light coupling to the SOS waveguide was experimentally confirmed.
