The ongoing growth of data traffic from existing and new applications poses a challenge to the packet-switched network infrastructure. High-capacity transport can be achieved in such networks by… (More)
The design and performance of several generations of wavelength-selective 1/spl times/K switches are reviewed. These optical subsystems combine the functionality of a demultiplexer, per-wavelength… (More)
We present results of the IRIS project, a DARPA-MTO funded program to develop a router with an all-optical data plane and a total capacity of more than 100 Tb/s.
A 1296-port MEMS transparent optical crossconnect with 5.1dB/spl plusmn/1.1dB insertion loss at 1550 nm is reported. Measured worst-case optical crosstalk in a fabric was n38 dB and nominal switching… (More)
We propose and demonstrate a novel compact N×M wavelength selective cross connect based on a single LCOS array with flexible pass bands. Prototype with 5 fully connected ports was demonstrated.
The effect of p-type doping of the active region of multiple quantum-well (MQW) semiconductor optical amplifiers (SOAs) has been studied. Spectrogram measurements of the dynamics of the SOAs reveal… (More)
The design of optical packet routers poses significant challenges both in terms of its architecture and component design. In this paper, we evaluate several alternatives for the architecture of such… (More)
This paper describes a continuously variable and independently addressable channelized dispersion compensator. The optical system is a free-space grating-based system used in a four-pass… (More)
We demonstrate the interconnection of two optical packet switching systems: a hybrid optoelectronic packet router and two optical packet rings. Error-free inter-ring and intra-ring optical packet… (More)
An all-optical wavelength-switch module at 40 Gb/s is monolithically integrated in InP by combining an SOA-based wavelength converter and a fast-tunable 8-channel multi-frequency laser. Error-free… (More)
