we design and simulate a five-port optical router, which is composed of twenty mach-zehnder-based switching elements and twelve waveguide crossings for use in integrated photonic interconnection networks. we simulated and analyzed the operation of the proposed optical router from the aspects of insertion loss, power budget, q-factor and the minimum bit error ratio by use of optisystem simulator...

We propose a universal method for constructing N-port non-blocking optical router for photonic networks-on-chip, in which all microring (MR) optical switches or Mach-Zehnder (M-Z) optical switches behave as 2 × 2 optical switches. The optical router constructed by the proposed method has minimum optical switches, in which the number of the optical switches is reduced about 50% compared to the r...

We present simulation results of an ultrafast all-optical router and a technique for separating the clock synchronization pulse from an incoming optical time division multiplexed data packet, based on all optical switches employing optical feedback. Three terahertz optical asymmetric demultiplexers (TOADs) have been used to model a 1x2 router. Simulation results show that synchronization betwee...

layer is the third component, the optical switch, which interconnects the core routers via a switched optical network layer over WDM links. While new high-availability (so-called “non-stop routing”) core routers provide service resiliency at the packet layer, the optical layer provides lowest cost and highest level of resiliency at the physical layer against catastrophic network events such as ...

We review the first InP monolithic tunable optical router chip, consisting of eight wavelength converters and an 8x8 AWGR. The device integrates more than 200 functional elements and operates at 40 Gbps per port. ©2010 Optical Society of America OCIS codes: (250.5300) Photonic integrated circuits; (060.1155) All-optical networks

Photonic packet switches can offer high data rates and format transparency as required by future communication system. Although electronic technology can achieve high switching speed, it is not compatible with the transmission bandwidths of the fiber-optic links. This paper is concerned with alloptical time division multiplexing router based on all-optical switching device. Three terahertz opti...

We experimentally demonstrate a spatially non-blocking five-port optical router, which is based on microring resonators tuned through the thermo-optic effect. The characteristics of the microring-resonator-based switching element are investigated to achieve balanced performances in its two output ports. The optical router is fabricated on the SOI platform using standard CMOS processing. The eff...

A new all-optical networking function is demonstrated using a bank of novel thermallytuned FBG-based optical correlators to construct an “optical bypass” to vastly accelerate conventional electronic internet routers. Based on a simple set of rules, a software algorithm configures the correlators as a routing table cache that can quickly determine the destination port for a large percentage of t...
