| 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 scal e of the photonic network on-chips.Silicon photonic devices based on SOI platform provi de a feasible technical scheme for optical router with low delay and power-effeicent on accou nt of the advantages in the aspects of bandwidth,delay and power-efficient.This paper r eviews a 4×4non-blocking wavelength select router based on two-order cascaded ring resonat ors.The two- order cascaded ring resonators which constitute the optical router can take shap e of box filter spectrum well.The width of the ridge waveguide is 450nm,the height of t he waveguide is 220nm,the ridge height is 60nm.The 3dB bandwidth is 0.3nm,the extinction ratio is 35dB and the in-band power fluctuation is 0.1dB.All of these provide a good experim ental basis for the optical router.The wavelength selective router has nine non-blocking l ines.It can implement four broadcast mode routing.It can be used as a basic optical switchi ng unit to cascade multiple routers to build a more powerful networks-on-chip. |
