TY - JOUR AU - Zhang, Da-Ming AB - Device architecture and design scheme of a universal $$N$$ N -stage cascaded polymer four-port optical router with scalable 3 $$N$$ N channel wavelengths are proposed. Basic cross-coupling two-microring resonator routing element based on polymer materials is optimized for single-mode transmission, low optical loss and phase-match between microring waveguide and channel waveguide. Then, a one-stage four-port optical router is constructed using four-group basic routing elements, which has 12 possible I/O routing paths and 3 channel wavelengths. The insertion losses of each channel wavelength along every routing path are within the range of 0.04–0.63 dB, the maximum crosstalk between the on-port along each routing path and other off-ports is less than $$-39$$ - 39  dB, and the device footprint size is $$\sim $$ ∼ 0.13 mm $$^{2}$$ 2 . Compared with the previously reported four-port silicon optical routers, this device possesses similar ring radius ( $$\sim $$ ∼ 10  $$\upmu $$ μ m) and device size ( $$<$$ < 1 mm $$^{2})$$ 2 ) . Aiming at wideband signal routing applications, we then construct a universal $$N$$ N -stage cascaded polymer four-port optical router possessing scalable 3 $$N$$ N channel wavelengths. The proposed routing structure has potential application in photonic networks-on-chip, because of low insertion loss, low crosstalk, small footprint size, and scalable wideband 3 $$N$$ N routing wavelengths.
