We model the nonlinear response of a silica toroid microcavity using coupled-mode theory and a finite-element method, and successfully obtain Kerr bistable operation that does not suffer from the thermo-optic effect by optimizing the fiber-cavity coupling. Our rigorous analysis reveals the possibility of demonstrating a Kerr bistable memory with a memory holding time of 500 ns at an extremely low energy consumption.
