HDETIN04-20G-L

Overview

LBTEK high-speed biased photodetectors cover Si, InGaAs, and GaAs sensor types with wavelength ranges spanning 400-3600 nm. These detectors combine low noise, high-speed response, and zero-gain characteristics for demanding applications.

Available in both free-space and fiber-coupled configurations. Fiber-coupled models accept FC/PC single-mode or multimode fibers. Free-space models offer either AR-coated flat windows or uncoated ball lenses for flexible input coupling.

Key Features

  • Wavelength coverage: 400-3600 nm (model dependent)
  • Rise time as fast as 17 ps
  • Free-space or fiber-coupled (FC/PC) input
  • SMA RF output connector (50 Ω)
  • External DC power supply included

Applications

  • High-speed optical communications
  • Ultrafast laser pulse characterization
  • Time-resolved spectroscopy
  • Optical heterodyne detection
