Adiabaticity Engineered Silicon Polarization Independent 3-dB Coupler for the O-Band

We demonstrate a compact and broadband polarization independent 3-dB coupler for the O-band on silicon-on-insulator platform. Using the multi-parameter adiabaticity engineering protocol, unwanted coupling between eigenmodes in mode evolution couplers are redistributed for dual polarization modes and...

Zusammenfassung:We demonstrate a compact and broadband polarization independent 3-dB coupler for the O-band on silicon-on-insulator platform. Using the multi-parameter adiabaticity engineering protocol, unwanted coupling between eigenmodes in mode evolution couplers are redistributed for dual polarization modes and multiple wavelengths, resulting in a large operating bandwidth for both TE and TM polarizations. The fabricated device has a bandwidth of 70 nm with a compact mode evolution region of 27 μm.
