Voxtel Releases High-Speed NIR APD Receivers

Source: Voxtel, Inc.

Voxtel has announced the release of an avalanche photodiode (APD) receiver with 1-gigahertz bandwidth and a large 200-µm-diameter optical area. The company believes it to be the highestbandwidth large-area NIR APD receiver, which makes it optimal for a broad range of laser rangefinders and laser designators, and for applications in free-space optical communications, optical instrumentation, and LADAR/LIDAR.

The model RIP1-NJAC APD photoreceiver is the latest entry in Voxtel's Siletz™ line of single-carrier multiplication avalanche photodiode (SCM-APD) products. The receiver integrates the low-excess-noise SCM-APD with a lownoise transimpedance amplifier (TIA). Voxtel's Siletz™ SCM-APDs are the lowest-excess-noise NIR–SWIR APDs available (with an equivalent ionization coefficient keff < 0.02), and allow for the receiver to operate at high avalanche gain, boosting the optical signal over the amplifier noise level without the degrading effects of avalanche-induced excess noise. The ultra-low excess noise and high gain make the RIP1-NJAC the most sensitive photoreceiver available on the market, offering a maximum responsivity over 50 A/W at 1550 nm, with operating gain up to 50.

A single-stage thermoelectric (TE) cooler is included to eliminate temperature-induced gain variation and allow optimal performance over the range of application environments. The receiver is available with an optional fiber pigtail.

The product is immediately available for sale.
