Abstract

Carrier transport significantly affects the high-speed dynamics of quantum-well lasers. Adverse transport properties lead to severe low frequency rolloff in the modulation response and also lead to a reduction in the dynamic differential gain of the lasers. The same transport properties also adversely affect the wavelength chirp in these lasers. As in the case of device optimization for high-speed operation, one has to minimize the transport time across the optical and current confinement regions and maximize the escape time out of the quantum-well active region, to minimize wavelength chirp.
