Request InfoVoxtel Inc.Voxtel Inc. has unveiled its carrier multiplication devices, a new class of near-IR photodetectors. The nanostructured InGaAs/InAlAs instruments are designed to overcome the limitations of avalanche photodiodes in the 0.9- to 1.6-μm spectral range. They exceed the capabilities of avalanche photodiodes in gain and noise performance and deliver high quantum efficiency, making them suitable for low-light-level detection, along with applications such as Raman spectroscopy and quantum cryptography.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueExtended InGaAs DetectorsHermetically sealed, surface-mount device-packaged 1.7- and 2.6-μm InGaAs PIN ATLAS photodiodes from Marktech Optoelectronics Inc. are designed for spacecraft, aerospace, medical, defense,...Photonics Spectra December 2022 IssueSilicon Photodiode ChipsThe VTH21 series of photodiodes from Excelitas Technologies Corp. are low-capacitance silicon photodiode chips for radon gas detection.
