Researchers from IBM have developed a prototype of an optical chipset developed with a throughput of 1 terabit per second. The researchers have for this Holey Optochip transceiver uses parallel communication.
The researchers to create the prototype of the optical interconnect, by the scientists Holey Optochip baptized, using a standard-cmos-siliciumhalfgeleider of 90nm, which 48 holes are made. This stitches 24 fotodiodes for the ontvanggedeelte and 24 ‘of the vertical-cavity surface-emitting lasers, or vcsel, to produce the light pulses. The fotodiodes and lasers are on the back of the chip soldered.
The lasers have a wavelength of 850nm and the Holey Optochip measures at 5.8 5.2 millimeters. The optical interconnect can be a throughput reaching 1Tb/s and is thus eight times as fast as existing parallel optical components. Despite the high speed consumes the chip is less than 5W.
The Holey Optochip is designed via an optical system on the basis of micro-lenses can be directly connected to existing 48-channel-multi-mode fiber arrays. The chip seems to be suitable for mass production.
IBM presented details about the prototype of Holey Optochip at the Optical Fiber Communication Conference in Los Angeles. At the same conference to present IBM researchers also information on a vcsel-link with a throughput of 15Gb/s at a power consumption of 20mW and a 40Gb/s vcsel link.
