In-situ Active Region Temperature Measurement for THz Quantum Cascade Lasers

Not Accessible

Your library or personal account may give you access

Abstract

The active region temperature of THz quantum cascade lasers during continuous-wave operation was measured using interband photoluminescence technique. The active region was found to be ~40K above heat sink temperature at maximum THz power output.
