Abstract
Concept, basic physics and modeling results of a novel modulation technique, associated with a variable heating of the electron-hole plasma in the active region of a lasing device, are reviewed with respect to the ultimately high-speed performance of semiconductor lasers. It is shown, that independent control of the plasma concentration and temperature provides a way for generating the picosecond gain-switched optical pulses and multi-Gbit/s modulation with, optionally, no parasitic frequency chirp. To practically realize this method, three-terminal laser structures are suggested, in which two bias voltages are intended to drive the pumping rate and the energy, yielded in the active region plasma as a result of injecting a single electron.
