Ultra-compact wavelength division multiplexing devices using silicon photonic wires for on-chip interconnects

摘要

Ultra-compact four-channel wavelength division multiplexing (WDM) devices in add/drop filter and multi-mode interferometer configurations were demonstrated on silicon-on-insulator for future on-chip optical interconnects. Both devices show a crosstalk level les-13 dB and a footprint les0.006 mm².
