Request InfoVoxtel Inc.Voxtel Inc. has introduced a collection of avalanche photodiodes (APD) for high-bandwidth, near-infrared optical applications. The devices feature a spectral response from 0.9 to 1.7 μm and low dark current. The company’s heterostructure InGaAs APD technology suppresses excess multiplication noise by a factor of three, improving the signal-to-noise ratio of the detector. The photodiodes are available in 25-, 75- and 200-μm diameters and in a variety of package formats.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2022 IssueOptical Spectrum AnalyzersThe AQ6375E and AQ6376E optical spectrum analyzers from Yokogawa Europe BV, Test & Measurement combine short- and mid-wavelength IR with extreme optical precision to aid in the development of...Photonics.com 12/12/2022Optical Sensing InterrogatorsFemto Sensing International has expanded its SX line of optical sensing interrogators for high-sensor-count fiber Bragg grating (FBG) applications.
