Bandfilling and photon-assisted tunneling in a quantum-well transistor laser
Abstract
Data and a phenomenological model for quantum-well (QW) transistor laser operation are presented showing, via the three-port input-output (electrical and optical) characteristics, the strong QW to collector coupling and the influence of bandfilling (QW states, Δhν recombination radiation, sensitivity of Eλ0→Eλ1,λ0→λ1,λ0>λ1) on base-to-collector photon-assisted tunneling and laser operation. Transistor (electrical) and laser (optical) operation are locked and “slide” up and down as a function of base current (IB), collector-base voltage (VBC or VCE), and the influence of QW bandfilling (with increased sensitivity at Eλ0→Eλ1) on photon-assisted base-collector tunneling.
