WARREN, N.J. -- Anadigics Inc. here today announced that it has developed a 12-channel metal-semiconductor-metal (MSM) photodetector array for use in 2x Fibre Channel, and Infiniband datacom networks capable of data rates up to 3.125 gigabits per second per channel.
The devices, which integrate a 1x12 array of photodetectors on a single gallium arsenide (GaAs) substrate, operate at 850 nm with a polarity-independent architecture. The optical MSM array is fabricated at Anadigics' state-of-the-art 6-inch GaAs production facility.
"Parallel optical communication systems are emerging as solutions for increased bandwidth applications," said Bami Bastani, president and CEO of Anadigics. "This highly integrated photodetector array, coupled with optical link laser arrays, will provide the industry with scalable broadband fiber interconnects for networking and fiber optic backplanes."
Bastani explains that transmit and receive arrays provide space efficient, broadband physical layer building blocks for high density fiber optic parallel interconnects.
Anadigics' MSM technology integrates all 12 channels on a single die, conforms to the 250-micron-pitch fiber ribbon cables, and displays superior crosstalk isolation while targeting responsivity in excess 0.4 amps per watt. With this scalable architecture, the company can produce a family of products from 1x4 up to the 1x12 technology recently demonstrated, Bastani said.
