A Free Space Optical Crossbar Switch Using Wavelength Division Multiplexing and Vertical-Cavity Surface-Emitting Lasers

Building large crossbar switches for low-latency, highbandwidth interprocessor interconnects in multiprocessor systems is a difficult task because of the many practical limitations of digital electronics. This paper presents a first order design for a crossbar switch which utilizes wavelength tunable vertical-cavity surface-emitting laser (VCSEL) technology and free space optics. Free space opt...

All-optical crossbar switch using wavelength division multiplexing and vertical-cavity surface-emitting lasers.

A design for an all-optical crossbar network utilizing wavelength-tunable vertical-cavity surface-emitting laser (VCSEL) technology and a combination of free-space optics and compact optical waveguides is presented. Polymer waveguides route the optical signals from a spatially distributed array of processors to a central free-space optical crossbar, producing a passive, all-optical, fully conne...

Optimal wavelength-space crossbar switches for supercomputer optical interconnects.

We propose a most economical design of the Optical Shared MemOry Supercomputer Interconnect System (OSMOSIS) all-optical, wavelength-space crossbar switch fabric. It is shown, by analysis and simulation, that the total number of on-off gates required for the proposed N × N switch fabric can scale asymptotically as N ln N if the number of input/output ports N can be factored into a product of sm...

Role of negative dielectric and optical quantum dot waveguiding methods in communication

While the application of optical and photonic technologies in the communications, computing, medicine and industrial manufacturing has been growing rapidly, the miniaturization of these technologies has been slow due to the limitation on the diffraction. However, the developments of nanoscale components and guiding methods are continuing with a rapid pace. Since waveguiding is a fundamental iss...
