New Focus(TM) (Santa Clara, CA), a Newport Corporation Brand, has introduced the GHz Nirvana(TM) High Speed Receiver, the world's only photoreceiver with automatic balancing. The new GHz Nirvana features 2000 times higher bandwidth and new fiber coupling, along with completely automatic signal balancing. The patent-pending auto-balance feature allows elimination of background noise from dynamically changing systems, including thermal drift and wavelength dependence, allowing you to achieve perfect power balance between the reference and signal beams. It also eliminates the need to optically balance the detectors, simplifying optical and electrical alignment. The GHz Nirvana Receiver has an operating wavelength range of 900 - 1650 nm and can cut the effects of laser noise by 25 dB, making even very small signals easy to see. Rise time is less than 1 ns and peak responsivity is 30,000 A/W.
