PRESS RELEASE

New Product Announcement: 2.2 um SWIR InGaAs Linear AGC Balanced Optical Receiver to 18 GHz


Discovery Semiconductors is pleased to introduce a 2.2 um balanced receiver with adjustable gain and bandwidth up to 18 GHz. This new device, with longer wavelength response of 1.2 um through 2.2 um, fits nicely with advances in real time scopes and 2.05 um ring and disk lasers.

Potential applications for Discovery's DSC-R212 include: laser development, gas detection, LIDAR, fast time resolved spectroscopy, non-linear frequency conversion, multi-octave spanning laser frequency combs, OFDM, laser photo medicine and photo surgery. Laser surgery is aided by a C=O absorption at 2.05 um and the ability to deliver the light through the fiber.


Salient Features:
• High responsivity from 1.2 um - 2.2 um optical wavelengths
• Well-matched fiber length, responsivity and RF response
• Automatic gain control (AGC) or manual gain control
• User-adjustable differential gain: 60 to 5600 V/W
• User-adjustable RF bandwidth and frequency response
• Peak detector function for monitoring of AC output voltage
• Wide optical dynamic range: -15 to 0dBm
• Low power consumption (270mW)
• Available in both module and Lab Buddy instrument formats
