Phase-Bistability and phase-locking patterns with cavity soliton in Vertical-cavity-based fast semiconductor saturable absorber.

A long-wavelength-operation based phase-bistabilty and phase-locking patterns is described analytically and numerically in a nonlinear Fabry-Perot (F–P) cavity packed with fast semiconductor saturable absorber. With incident power thermo-optic effects of absorbing film and cavity heating can offer a generation of red-shifted resonances due to increase of cavity temperature. With proper signal wavelength at particular top mirror reflectivity, the cavity phase-shift in F–P cavity with saturable absorption property may enhance an X-bistabilty in phase and phase-locking patterns with cavity soliton, where the both thermal and carrier diffusion time of semiconductor materials are assumed at faster time scale (i.e. pico-second or sub-pico-second). Also, a dual cavity solitons are observed with variation of input power due to contest between absorption nonlinearity and nonlinear cavity phase-shift for temperature "rocking".
