Intevac Intros Photodiodes

SANTA CLARA, Calif. -- Intevac, Inc. (NASDAQ: IVAC) has introduced new high-speed PIN-type photodiodes for integration into the receivers and transceivers of optical communication systems operating at OC-192 (10 Gigabit/sec) and OC-768 (40 Gigabit/sec). Photodiodes are the basic circuit element that converts optical pulses to electrical signals.“Our new patented photodiodes are for customers building high speed receivers and transceivers,” said Dick Lavine of Intevac’s Photonics Technology Division. “We are providing an easy to integrate device that’s backed by our over ten years’ experience working with Indium Gallium Arsenide – Indium Phosphide (“InGaAs-InP”) technology. These unique photodiodes are fabricated at our own facility, so we can respond to requests for special variations very quickly.”In the 1300- to 1550-nm range, the photodiodes are specified at 0.8 A/W for 10 Gigabit/sec devices and 0.5 A/W for 40 Gigabit/sec devices. For maximum engineering versatility and to keep cost to integrators at a minimum, the photodiodes are available as unpackaged 0.5 x 0.5 mm die and can be furnished with metallization patterns suitable for wire bond attachment or for flip chip packaging with other circuit elements.Intevac Inc.
