Abstract :
Simple analytical expressions, describing the performance of the Y-junction as a function of only one parameter, the mode conversion factor (MCF), are derived. The expressions are based on numerical studies of Y-junctions with varying MCFs by means of the finite-difference beam propagation method (FDBPM). The simple expressions are compared with published switching curves of electro-optic Y-junction switches and found to be in excellent agreement.
