Polarization dynamics induced by parallel optical injection in a single-mode VCSEL

Abstract

We report an experimental study of the polarization nonlinear dynamics in a 1550 nm single-mode vertical-cavity surface-emitting laser (VCSEL) subject to parallel optical injection. Experimentally measured stability maps identifying regions of different nonlinear dynamics for various values of bias current are reported. We show that VCSELs with more than a 35 dB polarization mode suppression ratio can have rich nonlinear dynamics in both linear polarizations, including periodic and chaotic behaviors appearing simultaneously in both polarization modes.

Polarization Effects on Photonic Microwave Generation in VCSELs Under Optical Injection

“…This dynamics, termed as P1-both, was observed for a VCSEL with a much higher value of the birefringence, p = 103.1 ns -1 . Our results are in agreement with the experiments because the frequencies of the oscillations in the P1-both state are close to the relaxation oscillation frequency [16]. Microwave Power (arb.…”

“…The P1 dynamics in both linear polarizations illustrated in Fig. 2 has been experimentally observed in [16]. This dynamics, termed as P1-both, was observed for a VCSEL with a much higher value of the birefringence, p = 103.1 ns -1 .…”

1/ f noise in the intensity fluctuations of vertical-cavity surface-emitting lasers subject to parallel optical injection

“…A detailed description of the experimental setup used in this work can be found in [5]. In essence we have a tunable master laser that injects the parallel polarized light into the slave laser (VCSEL) through an optical circulator.…”

“…In IL+PS, injection locking of the parallel polarization and excitation of the free-running orthogonal polarization are simultaneously observed. The fluctuation dynamics of this new state, when (in a parameter space) it is on the frontier with other states, presents interesting features [5][6][7].…”
