A CMOS Compatible On-Chip MMI based Wavelength Diplexer with 60 Gbit/s System Demonstration

An ultra-compact
$(41\mu \mathrm{m})$
1310/1550 nm diplexer with an insertion loss < 1 dB and extinction ratio > 20 dB for both the wavelengths is demonstrated. Furthermore, experiments show clear eye diagrams at 60 Gbit/s signals. © 2022 The Author(s)
