An ultra-compact, polarization-independent, dual-channel wavelength demultiplexer is designed by the inverse method with a footprint of 2.5µm × 2.5µm. The topology optimization-based inverse design method is used for designing the device. It is designed on the CMOS-compatible silicon on Insulator (SOI) platform. The peak transmission obtained for quasi-TE polarization at 1310nm and 1550nm is approx -1.0 dB and -1.7 dB respectively and for quasi-TM polarization at 1310 nm and 1550 nm is approx -1.0 dB and -1.9 dB respectively. © 2023 SPIE.
