Photodetector Buyer’s Guide
Choosing the right photodetector is critical for achieving accurate, reliable optical measurements. This guide explores key selection factors, including wavelength range, responsivity, speed, noise, and packaging, to help engineers match detector performance to specific applications across telecom, industrial, and scientific systems.
Photodetector Selector
Answer four questions about your application — wavelength range, response speed, signal strength, and beam tracking — and our Photodetector Selector points you to the detector type best suited for your system. A parameter reference table breaks down the datasheet values, including responsivity, dark current, bandwidth, and active area.
InGaAs and Germanium Photodiodes: Critical Infrastructure for Data Center Buildout Plans
As AI data centers scale toward 800G and 1.6T networks, copper wiring has hit its physical limits. Discover why InGaAs and Germanium photodiodes have become essential components for converting optical signals back into data, powering everything from short-reach links to long-haul interconnects.
Fundamentals of Light Detection
This is a practical guide for engineers, covering semiconductor physics, PN junction behavior, and all major detector types, including PIN, APD, and Schottky designs, with material comparisons across silicon, germanium, and InGaAs. Specialized geometries such as quadrant cells, tetralateral position-sensing detectors, and sandwich detectors for two-color detection are explained.
