Bias-free, low power and optically driven InP on SOI switch for remotely configurable photonic packet switches

Abstract: First ever demonstration of an InP-on-SOI switch for all-optical-packet-switching The switch has 300/1300psec on/off switching times, >30dB extinction-ratio and no measurable pattern dependence or switch related power penalties up to a bit rate of 40Gb/sec

Logical clustering for the optimization and analysis of a rearrangeable distributed ATM switch

Abstract: A practical approach to the analysis and operation of medium to large-size distributed asynchronous transfer mode (ATM) switches based on an original optical reconfigurable architecture is described. The optical nature of the switch provides enormous bandwidth with input/output port rates on the order of gigabits/second, and the distributed approach is highly modular, creating an easily growable switch. The interconnection pattern between input and output ports is dynamically reconfigurable; the switch can thus exploit nonuniformities in the offered traffic and optimize its connectivity accordingly. For a 24*24 switch, this leads to performance that matches that of a fully connected output buffered ideal centralized switch. Simulation results for a switch of size 81*81 seem to indicate that the traffic-handling capability scales well with the size of the switch when nonuniformity prevails in the offered traffic, a realistic assumption. Clustering techniques would permit the optimization and operation of much larger reconfigurable distributed ATM switches. >

Core Switch Architectures for the Agile All-Photonic Network: Performance Evaluation with Crosstalk

Abstract: The aim of this work is to analyze, evaluate, and compare the technological and architectural options to implement the core switches of the Agile All-Photonic Network (AAPN). The required core switch functionality and switch scales are discussed. Three technological choices, Electro-optics, SOA optical gates, and TWC with AWG are considered. The major performance impairment in optical switches, the in-band crosstalk, is analyzed using a statistical model to evaluate and compare its impact up on the scaling of the switch fabrics. The switch element crosstalk requirement is estimated as a function of switch dimension and a suitable technology option that is realistic for various switch capacities is presented.

Optical switch architecture

Abstract: An optoelectronic switch for transferring a signal from an input device for an output device, the optoelectronic switch including: a plurality of leaf switches, each having a radix R , and arranged in an L -dimensional array, in which the i -th dimension has a size R i where ( i = 1, 2,..., L ) and for a reduced dimension, R i is less than for all of the other dimensions, each leaf switch having an associated L -tuple of coordinates ( x 1 ,..., x L ) giving its location with respect to each of the L dimensions; wherein each leaf switch is a member of L sub-arrays, each of the L sub-arrays associated with a different one of the L dimensions, and including: a plurality of R i leaf switches whose coordinates differ only in respect of the i -th dimension, each leaf switch having C client ports for connecting to an input device or an output device.

Design of Two-Dimensional Optimized Banyan Networks

Abstract: A smart two-dimensional optical Banyan network is proposed. Polarization switching logic of light is applied for the design of this network. The main element for the connections of the network is an optical crossbar switch that is composed of a half-wave plate, a programmable polarization switch, and a couple of birefringent plates. By the proposed optical crossbar switches, all permutations of the link patterns required in the network are generated due to the optimized design of the switching logic. As a result, complicated routing control of ordinary Banyan networks is much reduced and a simple two-dimensional optical Banyan network with straight interconnections between successive stages of the networks can be realized.
