Function-Versatile Thermo-Optic Switch Using Silicon Nitride Waveguide in Polymer
A function-versatile thermo-optic switch is proposed and experimentally demonstrated using silicon nitride waveguides embedded in polymer cladding. The device consists of a 1 × 2 input splitter, 2 single-mode waveguides for phase shifting, and a thermally controlled 2 × 2 output coupler to give anot...
