Resonant Dynamics of Nonlinear Optical Microdisks

An investigation into the relationship between two-photon-induced carrier dynamics and nonlinear optical resonance is carried out for an InP microdisk. A phenomenological model is developed and algebraic solutions are presented for the resulting bistability turn-on and turn-off transition points. It is shown that the offset between the operating wavelength and the un-illuminated resonance wavelength plays a critical role in defining the optical bus line intensity requirements at the input and the intensity contrast ratio at the output.
