Stabilization of the vertical cavity surface emitting laser subject to asymmetrical triangular current modulation

We investigate the effect of external optical injection on the dynamics of the vertical cavity surface emitting laser under asymmetrical triangular modulation theoretically. The vertical cavity surface emitting laser with asymmetrical current modulation emits irregular optical pulses both in amplitude and in polarization. In this paper we demonstrate that optical injection leads to stabilization of laser output. Laser with injected signal emits regular subnanosecond optical pulses. Dependence of statistical characteristics of emitted pulses from injected signal parameters is investigated.
