Side-mode resonance in a Fabry-Perot semiconductor laser with intermodal injection

Summary form only given. Optical injection in semiconductor lasers has been studied extensively and many effects of optical injection on the behaviour of the semiconductor lasers have been reported. We provide what we believe to be the first report of several new regimes in intermodal injection of semiconductor lasers. The most significant newly-identified regime is a side mode resonance regime. Here the side mode becomes the dominant lasing mode and, instead of injection locking occurring, the SL wavelength is switched from the free-running wavelength to the side mode wavelength. We also observed that nondegenerate four wave mixing (NDFWM) arises in the positive detuning regime.
