简介
An on-chip silicon TE-pass polarizer is proposed and demonstrated. The proposed polarizer is realized by asymmetrical directional couplers assisted with sharp bending and tapered waveguides. The TM 0 mode is converted into TM 1 mode through the asymmetrical directional coupler and then filtered out by the bending and taper, while TE 0 mode goes through with negligible coupling due to the phase mismatch. The measured extinction ratio at central wavelength is 29.8 dB, while the -15 dB bandwidth is >80 nm.
