Exploiting Wavelength Division Multiplexing for Optical Logic Synthesis

Photonic integrated circuit (PIC), as a promising alternative to traditional CMOS circuit, has demonstrated the potential to accomplish on-chip optical interconnects and computations in ultra-high speed and/or low power consumption. Wavelength division multiplexing (WDM) is widely used in optical communication for enabling multiple signals being processed and transferred independently. In this work, we apply WDM to optical logic PIC synthesis to reduce the PIC area.
