Abstract :
THz-Quantum Cascade Lasers (THz-QCLs) are expected as light sources for high-speed communication because their potential of high-speed modulation is predicted by theory. We have built THz-QCLs light-current characteristics measurement system, in which optical and current pulses were synchronized. And the reduction of output from THz-QCLs was observed with external optical pulse injection.
