SPD optical module

SPD optical modules are high-sensitivity single-photon detection devices that convert individual photons into electrical signals, optimized for visible and near-infrared applications. OverviewSPD (Single-Photon Detector) optical modules are designed to detect extremely low levels of light, down to individual photons. They typically use Single-Photon Avalanche Diodes (SPADs) operating in Geiger mode, which allows the module to generate a digital pulse for each detected photon.

These modules are widely used in quantum optics, quantum communication, LIDAR, and high-precision sensing applications.

Key Features

Wavelength Range: SPD modules cover visible to near-infrared spectra. For example, Aurea SPD_OEM_NIR operates from 900–1700 nm, while Dimension Labs modules cover 400–1700 nm.

SIMTRU

M offers modules from 200–1600 nm for Si-APDs and 900–1700 nm for NIR SPDs. Photon Detection Efficiency (PDE): Efficiency varies by wavelength and technology. Aurea modules achieve up to 30% at telecom wavelengths, while Dimension Labs Si-SPDs can reach 60% at 650 nm.

Dark Count Rate (DCR): Low DCR is critical for accurate photon counting. Aurea SPD_OEM_NIR modules have DCR
