Silicon-InGaAs Photodetectors Deliver Reliable Broadband Detection

Nov. 12, 2019
Marktech’s MT03-041 and MT03-047 hybrid photodetectors offer 365-nm blue-green enhanced silicon-based and 1300-nm InGaAs-based detection.

Marktech Optoelectronics Inc. announced the global market introduction of two new broadband hybrid silicon-InGaAs photodetectors, the MT03-041 (TO-5) and MT03-047 (SMD).

The design of these models ensures versatile, accurate, and reliable broadband detection over spectral ranges of ultraviolet (UV) to visible (VIS) to short-wave infrared (SWIR), with 250- (UV) to 1750-nm (SWIR) enhanced sensitivity, says the company. This wide range includes 365-nm blue-green enhanced silicon-based and 1300-nm InGaAs-based detection, respectively; low-noise measurement performance; and high shunt resistance. The detectors are integrated within a single, compact through-hole or SMD package. They are also REACH- and RoHS-compliant.

Typical applications for the broadband hybrid silicon-InGaAs photodetectors include the medical and industrial industries involving high-speed communications, security, and spectroscopy.

Small-to-medium-sized quantities of standard models MT03-041 and MT03-047 are typically available with 24-hour shipment from stock via Marktech global distribution partner, Digi-Key Electronics. Optional accessories for are also available from Marktech, such as UV-to-infrared (IR)-to-SWIR range emitters. Each emitter may be mechanically and spectrally matched, then combined with the photodetector as a single, compact package. Custom designs may be produced in six to eight weeks from customer prototype approvals.
