Broadband TM-Mode-Pass Polarization Rotator and Power Divider With Tunable Beam-Splitting Ratio

A TM-mode-pass polarization rotator and power divider with an arbitrary beam-splitting ratio constructed by an adiabatic taper, a spatial mode order convertor and a multi-mode interferometer (MMI) is proposed on the silicon-on insulator (SOI) platform. Both arbitrary power splitting and polarization...

Description
Summary:A TM-mode-pass polarization rotator and power divider with an arbitrary beam-splitting ratio constructed by an adiabatic taper, a spatial mode order convertor and a multi-mode interferometer (MMI) is proposed on the silicon-on insulator (SOI) platform. Both arbitrary power splitting and polarization selection-rotation can be realized in this single device. The measurements show that a continuously adjustable beam-splitting ratio from 1:99 to 99:1 within a 33.2 mW power consumption from 1520-1580 nm has been realized for the proposed device.
