High-Extinction-Ratio and Compact 1310/1550 nm Wavelength Diplexer on SOI Platform Based on an SWG-Structured Two-Mode Interference Coupler
We propose a 1310/1550 nm wavelength diplexer on a 220-nm silicon-on-insulator (SOI) platform. The device is based on a compact two-mode interference (TMI) coupler enabled by a subwavelength grating (SWG) slot. The ideal beat length ratio of 2:1 is achieved with the transverse magnetic (TM) mode by...
