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...
متن کاملStarvation Free Scheduler for Buffered Crossbar Switches (RESEARCH NOTE)
Need for high speed internet connectivity has lead to a substantial research in switching systems. Buffered crossbar switches have received a lot of attention from both research and industrial communities due of its flexibility and scalability. Designing a scheduling algorithm for buffered crossbar switches without starvation is a major challenge as of now. In this paper, we proposed a Delay ba...
متن کاملWavelength Division Multiplexed Optical Interconnects Using Femtosecond Optical Pulses
The application of well-known concepts from the telecommunications industry to optical interconnects is common; however, significant modifications of the typical approaches may be required to keep costs low. We suggest such an approach by demonstrating the operation of a multiple channel chip-to-chip wavelength division multiplexed (WDM) interconnect through a single fiber using GaAs diodes fli...
متن کاملA 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...
