Ultra-wide band polarization insensitive photonic integrated filters and switches

We demonstrate polarization insensitive (PI) ultra-wide band (UWB) photonic filters and switches: 1×12 100 GHz spaced arrayed waveguide grating (AWG) on 3-µm silicon platform, photonic integrated 4×4 polymer matrix switch using total internal reflection (TIR) effect and integrated thermal-optic silica wavelength selective switch (WSS).
