Abstract:The transistor laser possesses advantageous characteristics of fast base spontaneous carrier lifetime, high differential optical gain, and unique three-terminal electrical-optical characteristics for direct “read-out” of its optical properties. These potentially lead to advantageous and useful features for designing high-speed optical transmitters that operate without the limitations of resonance, a feature common in the operation of semiconductor (two-terminal) diode lasers. The characteristics of the transistor laser are studied by considering the charge transport, and the coupling of the photon and quantum-mechanical electron-hole recombination dynamics in the operation of the transistor laser. An analytical understanding of these physical characteristics is developed based on experimental data, and a computational model of the transistor laser is developed for device engineering and circuit design applications.
