Abstract

We demonstrate a polarization-independent mode-evolution-based coupler for the silicon-on-insulator platform. The measured coupler has negligible insertion loss over a bandwidth of about 100 nm, i.e., from 1500 to 1600 nm. The measured maximum power imbalances for the polarization-independent coupler are 1.2 and 0.2 dB for the fundamental transverse electric (TE00) mode and the fundamental transverse magnetic (TM00) mode, respectively. Our coupler also has a compact design footprint with mode-evolution region not more than 75−μm long.
