Abstract
Data are presented showing open-eye 20-Gb/s transmission for a quantum-well transistor laser operating at room temperature (25 C). The fast spontaneous recombination lifetime (sim30 ps) in the base region results in a resonance-free frequency response allowing demonstration of 20-Gb/s transmission with an I I TH=3. It is shown that higher temperature hastens the transition to the first excited state and improves bandwidth and eye-opening at low bias levels I}I TH=2). In addition, room temperature 20-Gb/s transmission through voltage modulation of a transistor laser via intracavity photon-assisted tunneling in the base-collector junction is reported.
