The paper discusses an experimental study of an optical switch that can be constructed using the adjustable Y-branch field-induced waveguides. A crosstalk of less than -18 dB is measured at a wavelength of 1.06-μm in a device with a transition length of 400 μm and a branching angle of 4°. The finite difference beam propagation method (BPM) was used in the numerical simulation which shows that a crosstalk of less than -22 dB can be expected for the same device dimensions. Field-induced waveguide loss based on proton implant isolation was included in the calculation.
