We propose that optical packet switching networks are better implemented through space division switching (SDS) approaches than through wavelength division multiplexing (WDM) approaches. We show that active optical networks designed from optically controlled nonblocking networks can provide higher efficiency and lower latency advantages compared to other approaches. Our self-routing optical crossbar network, VIPER+, is realized from locally controlled 2/spl times/2 electrooptic switches that…

The authors outline the switch architecture using VIPER+, and the projected performance based on analytical modeling, which relies on simpledistributed routing algorithms and uses cut-through switching to avoid buffering at the switch interface.
Designing Optical Networks from Simple Switching Elements
This thesis describes a new self-routing optical crossbar design, VIPER +, that can be realized by locally controlled 2 × 2 electrooptic switches and proposes a waveguide mesh interconnection network that incorporates an optical express router in an electrical mesh.
Self-routing crossbar packet switch employing free-space optics for chip-to-chip Interconnections.
A nonblocking cross bar network that employs free-space optical interconnections between optoelectronic switching nodes is proposed and a simple routing scheme is discussed that permits the optical crossbar network to be operated as a self-routing packet switch.
Performance of a broadcast packet switch
The results of a simulation study undertaken to evaluate a high-performance packet-switching fabric supporting point-to-point and multipoint communications are presented, finding that networks constructed from nodes with more then two input and output ports can perform less well than those constructed from binary nodes.
Dense Wavelength Division Multiplexing Networks: Principles and Applications
Recent progress in multiwavelength networks are reviewed, some of the limitations which affect the performance of such networks are discussed, and examples of several network and switch proposals based on these ideas are presented.
A collisionless multiple access protocol for a wavelength division multiplexed star-coupled configuration: architecture and performance analysis
A collisionless wavelength-division multiple-access (WDMA) protocol for a passive star-coupled photonic network is introduced and shown to possess significant performance and flexibility advantages.

The target of the architecture described here is the optoelectronic extension of the interconnect previously used in a shared-memory, distributed, MIMD supercomputer, and at a lower performance level this same architecture could also meet the growing near-term interconnect needs within and between current large computing centers.
Log2 (N, m, p) strictly nonblocking networks
The complexity and the fault-tolerant capability of the strictly nonblocking Log/sub 2/ (N, m, p) network are analyzed and the authors compare it to the Cantor network, which is also strictly non blocking and has similar characteristics.
Optical interconnections for massively parallel architectures.
A study of board-level interconnection requirements for highly parallel and massively parallel computing and the use of polymer waveguides appears to offer the best solution compatible with existing multiboard system architectures.
Demonstration of an integrated, active 4*4 photonic crossbar (for avionic systems)
A monolithically integrated, active 4*4 photonic crossbar switch has been fabricated by using rib waveguides with etched-facet T-branches and turning mirrors. Switching functionality, simultaneous
