Silicon Avalanche Photodiodes and Modules

Silicon Avalanche photodiodes

The silicon avalanche photodiode (Si APD) is a photon detection device that offers high internal gain. It is ideal for use in high speed, low light level applications. API also offers several patented large area configurations (LAAPD) enhanced for a variety of regions of the spectrum. These are available with built-in thermoelectric coolers to reduce the dark current and enhance performance. Package options include hermetically sealed windows or windowless configurations.

Technical data and operation of silicon avalanche photodiodes can be found in our application note section.
