Abstract

We report experimental measurements and numerical calculations of the effects of strong, nearly-degenerate optical injection in a nearly single-mode, Fabry-Perot laser diode. The noise spectra and the response to weak optical injection of the laser diode are well characterized by a model, based on the coupled electric-field and carrier-density equations, which includes the effects of gain saturation and the weak side modes. Beyond the perturbation regime, the laser exhibits new operating characteristics, including an output which involves rapid fluctuations among several longitudinal modes and spectral broadening of the principal mode. The laser dynamics strongly depends on the injected optical power and the frequency offset between the external input and the free-running oscillation. Numerical simulations are conducted using the full coupled-equation model for a strictly single-mode laser without noise.
