MQW tuned semiconductor lasers with uniform frequency response

MQW tuned semiconductor lasers with uniform frequency response
A tunable semiconductor laser with an intrinsically wideband uniform frequency response has been developed, using the quantum confined Stark effect in quantum well material as the tuning mechanism. A frequency response uniform within 3 dB from 20 kHz to 1.2 GHz was achieved, limited by the measuring system at low frequencies and by device capacitance at high frequencies. Analysis shows that with optimised tuning elements an uniform frequency response to over 50 GHz should be achievable with this technique.

Abstract

A tunable semiconductor laser with an intrinsically wideband uniform frequency response has been developed, using the quantum confined Stark effect in quantum well material as the tuning mechanism. A frequency response uniform within 3 dB from 20 kHz to 1.2 GHz was achieved, limited by the measuring system at low frequencies and by device capacitance at high frequencies. Analysis shows that with optimised tuning elements an uniform frequency response to over 50 GHz should be achievable with this technique.
