摘　　要：设计了一种基于串联双环谐振器的4×4无阻塞波长选择路由器。构成该路由器的串联双环谐振器具有良好的箱型滤波曲线,SOI脊波导截面尺寸为波导宽度450 nm,高度220 nm,脊高60 nm,微环半径为10μm,实验可得其3 dB带宽为0.3 nm,消光比为35 dB,带内功率起伏只有0.1 dB,为实现该路由器的功能提供了很好的实验基础。该波长选择路由器有九种非阻塞线路,能够实现四种广播模式路由,其可作为基本光学交换单元,级联多个路由器来构建更强大的片上光网络。As the key component for photonic network on-chips,optical router is used to exchange the data between the processor cores.It determines the reliability and the scale of the photonic network on-chips.Silicon photonic devices based on SOI platform provide a feasible technical scheme for optical router with low delay and power-effeicent on account of the advantages in the aspects of bandwidth,delay and power-efficient.This paper reviews a 4×4 non-blocking wavelength select router based on two-order cascaded ring resonators.The two-order cascaded ring resonators which constitute the optical router can take shape of box filter spectrum well.The width of the ridge waveguide is 450 nm,the height of the waveguide is 220 nm,the ridge height is 60 nm.The 3 dB bandwidth is 0.3 nm,the extinction ratio is 35 dB and the in-band power fluctuation is 0.1 dB.All of these provide a good experimental basis for the optical router.The wavelength selective router has nine non-blocking lines.It can implement four broadcast mode routing.It can be used as a basic optical switching unit to cascade multiple routers to build a more powerful networks-on-chip.
