Abstract
Eight-port optical routers are widely used in cluster-mesh photonic networks-on-chip (NoC). By using 24 groups of cross-coupling two-ring resonators, a 1-stage 8-port polymer optical router is proposed, which can optically route 7 channel wavelength data streams along definite path in two-dimensional (2D) plane. Under the selected 7 channel wavelengths, the insertion losses along all routing paths are within 0.02–0.58 dB, the maximum crosstalk of all routing operations is less than −39 dB, and the device footprint size is about 0.79 mm2. Then, a universal novel structure and routing scheme of N-stage cascaded 8-port optical router are presented, which contains 7N channel wavelengths. Because of the good scalability in wavelength, this device shows potential application of wideband signal routing in optical NoC.
