Abstract
- Spectral domains showing polarization-wavelength hysteresis regions up to 0.3 nm wide were observed when the emission frequency of a diode laser having a nearly polarization-independent confinement factor was tuned in a simple external cavity with grating. In these regions the laser emits in a stable single mode with either TE or TM polarization, depending on whether the region was entered from lower or higher wave-lengths. We explain the observed phenomenon on the basis of nonlinear gain saturation between TE and TM polarization. © 1995 IEEE
