构建了一种五端口聚合物光路由器,由于四种不同半径的交叉耦合双环谐振器的谐振作用,该器件可完成二维平面内对四个信道波长的定点路由功能。由于聚合物材料和左右覆层材料具有较大的折射率差,四种微环的半径可小至14μm,波导模式振幅弯曲损耗小于10-4 dB/cm。当不同信道波长沿不同端口输入时,得到了波长与路由链路的关系。计算结果表明,各信道波长沿各路由链路的插入损耗为0.03~0.62dB,各路由链路on端口和其他off端口的最大串扰小于-39dB,器件的尺寸约为626μm×495μm。与已报道的硅光路由器相比,该聚合物器件具有相似的微环半径和封装尺寸,且由于零静态功耗、低串扰、低损耗和处理工艺简单、价格低廉等优势,该器件在光片上网络中具有潜在的应用价值。 A five-port polymer optical router is constructed. Due to the resonant effects of four different cross-coupled double-ring resonators, the device can accomplish the fixed-point routing of four channel wavelengths in a two-dimensional plane. Due to the large difference in refractive index between the polymeric material and the left and right cladding materials, the radius of the four microrings can be as small as 14 μm and the amplitude-mode bending loss of the waveguide mode can be less than 10-4 dB / cm. When different channel wavelengths are input along different ports, the relationship between the wavelength and the routing link is obtained. The calculation results show that the insertion loss of each channel wavelength along each routing link is 0.03 ~ 0.62dB, the maximum crosstalk between the on port and other off ports of each routing link is less than -39dB, and the size of the device is about 626μm × 495μm. Compared with the reported silicon optical router, the polymer device has similar micro-ring radius and package size, and due to the advantages of zero static power consumption, low crosstalk, low loss, simple processing and low price, On-chip network has potential application value.
