VI Systems ships first circular VCSEL arrays for datacoms

VI Systems GmbH of Berlin, Germany has started to ship to selected customers the first circular arrays of its vertical-cavity surface-emitting lasers (VCSELs). The customized chip features seven independent channels with data rates of up to 5Gbit/s per channel, with VCSEL light emitters (with a specified operating wavelength of 850nm) arranged in a ring-like 6+1-channel configuration with one emitter in center.

Designed for wire-bonding as well as for flip-chip bonding, the VCSEL arrays can be contacted directly from the top and feature a high-speed pad layout.

Originally spun-out of the Technical University of Berlin and the A. F. Ioffe Physico-Technical Institute in St Petersburg, Russia, VI-Systems is a fabless developer and manufacturer of ultra-high-speed optoelectronic components, offering laser and photo-detector chips and modules for applications in optical data communications, industrial and consumer applications.

Target applications of the new circular VCSEL arrays are short-reach and very-short-reach optical receivers and transceiver modules used in optical communication networks as well in chip-to-chip optical interconnects in the computer industry. Future serial standards at data rates of 28Gbit/s are currently being developed within Common Electrical Interface (CEI-25/28Gbit/s), Fiber Channel 32Gbit/s  and Ethernet IEEE 40/100Gbit/s standards, as well as for a number of custom-specific applications.
