[IEEE 2018 IEEE 15th International Conference on Group IV Photonics (GFP) - Cancun (2018.8.29-2018.8.31)] 2018 IEEE 15th International Conference on Group IV Photonics (GFP) - Subwavelength-Grating-Based 4-Channel Add-Drop Multiplexers in Silicon Photonics

摘要： We demonstrate a compact silicon photonic 4-channel optical add-drop wavelength multiplexer enabled by subwavelength-grating-based contra-directional couplers. Pass-bands of the device show on-chip insertion losses below 1.3 dB with wide 3 dB bandwidth of ~ 6.7 nm suitable for coarse wavelength division multiplexing (CWDM) in short-reach optical interconnect applications.
