Abstract

A two-input configuration for microresonators, exhibiting bistability owing to Kerr nonlinearity, could be used for the realization of optical flip-flops with switching speeds that are not limited by thermal effects. We present design considerations for such devices. The concept of phase switching is explained, and the results of numerical simulations clarify the conditions under which it will succeed. A thermal model is presented and used to understand the influence of the material properties and cavity structure on important operating parameters that will be relevant to any experimental effort to realize the device.
