Directed Logic WDM-Based Scalable Optical Decoder Using Micro-Ring Resonators

A novel design for an optical decoder is demonstrated in which by using the Wavelength-Division Multiplexing (WDM) property of the micro-ring resonators, we greatly simplify the design and achieve scalability to produce N-bit decoders. We designed the decoder logic using directed logic. Directed logic takes the full advantage of integrated photonics and electronics and has received lots of investigation since its introduction. The feasibility of the proposed decoder is verified through simulation.
