Data are presented on a quantum-well (QW)-based (QW) heterojunction bipolar transistor laser modified with external (increased) mirror reflection yielding lower threshold current and higher collector breakdown voltage . Increased breakdown at lower currents is observed on the collector characteristics, at constant base current , as a slope change, a corner, and a narrow-line to broadband spectral shift from stimulated (high coherent optical field) to spontaneous (lower incoherent field) operation, a consequence of quenching or reducing photon-assisted tunneling (Franz-Keldysh effect) under the constraint as .
