Abstract

Optical injection into the ground state (GS) of a quantum dot laser nominally emitting from the excited state (ES) can induce a switch to GS emission. Antiphase oscillations are obtained consisting of short ES pulses with GS dropouts. These disappear when the master laser is sufficiently detuned or weak and CW emission from the (multimode) ES is regained. The pulses are accompanied by a notable expansion of the ES optical spectrum, which disappears abruptly when the system switches to the CW ES operation. The phenomenon arises due to the large difference in timescales between the ns scale pulses and the ps scale carrier distribution times of the quantum dots.
