Paper Abstract

We propose an all-optical switch that is composed of a symmetric Y-branch ion-exchanged glass waveguide with a strip of self-focusing polymer loaded on top of one branch and a strip of self-defocusing polymer loaded on top of the other branch. In terms of Jacobian elliptic functions, the nonlinear dispersion to explain the evolution of TE modes in the device was calculated. It is shown that the device can be used at relatively low input intensities. The factors affecting input power threshold and switching response of nonlinear wave propagation in the device are investigated in detail. To demonstrate nonlinear switching behaviors further, we employ a beam propagation method to simulate optical-field propagation in the Y-branch waveguide.
