Sub-Nanosecond Pulsed Quantum Cascade Laser Driver

A QCL modulator based on a pair of pulsed HEMT transistors was designed to test the high-speed VIGO System HgCdTe photodetectors response time. A drive current and optical pulse width of approximately 1A and 100ps, respectively, were achieved. © 2019 The Author(s)
