How Avalanche Photodiodes Work

The APD410 is ideally suited for applications requiring highest sensitivity for low level input signals in the UV to visible range.

An avalanche photodiode (APD) is a highly sensitive type of photodiode, which in general are semiconductor diodes that convert light into electricity

Simulate an Avalanche photodetector (APD) based on a Ge-on-Si heterostructure with the avalanche multiplication taking place in the Si layer.

Avalanche photodiode detectors have and will continue to be used in many diverse applications such as laser range finders and photon correlation studies. This ...

An Avalanche Photodiode (APD) provides higher sensitivity than a standard photodiode and is for extreme low-level light (LLL) detection and photon counting.

APDs are photodiodes with internal gain produced by the application of a reverse voltage. They have a higher signal-to-noise ratio (SNR) than PIN photodiodes.

Avalanche photodiodes (APDs) are used to detect extremely weak light intensities. Silicon (Si) APDs are used in the wavelength range from UV to NIR (250 nm to ...

Thorlabs' Free-Space Silicon Avalanche Photodetectors (APD) are designed to offer increased sensitivity and lower noise compared to standard PIN detectors.

Thorlabs and Menlo Systems, a Thorlabs strategic partner, offer several avalanche photodetectors that are ideal for detection of low optical powers.
