PDM-IR – SPAD Modules & Single-Photon Detectors by Micro Photon Devices (MPD)

Overview

The PDM-IR is a photon counting module based on an InGaAs/InP SPAD for the detection of near-infrared photons from 900 nm up to 1700 nm. The module includes a programmable frequency and pulse generator for gating the detector, a front-end circuit for photodetector’s avalanche sensing, a fast circuit for detector’s avalanche current quenching and operative bias voltage resetting, and some sub-circuits for signal conditioning. All the main parameters and delay paths are adjustable by the user through the software interface, in order to match the requirements of different applications. The system can be conveniently used both for counting and timing measurements, since the high-performance electronics guarantees a clean temporal response even with fast gate transitions. PDM-IR can work either in free-running or in gated mode (up to 100 MHz), the optical interface can be chosen between a free-space and a fiber version. Two fiber options are available: single-mode SMF-28 and 50 µm graded-index multimode fiber. In both cases, users can choose between a desktop instrument version, typically for laboratory use, and a more compact version, optimized for OEM applications.
