We present a photonic crystal configuration consisting of a waveguide directly coupled to two microcavities with instantaneous Kerr nonlinearity. We prove that such a configuration can function as a high contrast all optical switch with properly misaligning the resonant frequencies of the constitutional photonic crystal microcavities.

    We investigate a hybrid electro-optomechanical system that allows us to realize controllable strong Kerr nonlinearities even in the weak-coupling regime. We show that when the controllable electromechanical subsystem is close to its quantum critical point, strong photon-photon interactions can...

    We show a simulation for the free propagation of a Gaussian and multi-spatial soliton beam in a self-refractive waveguide through the Beam Propagation Method (BPM). We observed and conjectured that a Gaussian beam can be decomposed into Solitons by the propagation in a self-refractive media. We...
