What is Geiger mode operation?
In a single-photon-counting APD (in Geiger mode), the electric field described above increases with increasing applied voltage, thereby increasing the APD gain. The discharge-and-reset cycle is known as the Geiger mode of operation.
What is avalanche photodiode detector?
An avalanche photodiode (APD) is a highly sensitive semiconductor photodiode detector that exploits the photoelectric effect to convert light into electricity. From a functional standpoint, they can be regarded as the semiconductor analog of photomultipliers.
What is avalanche diode mode?
In electronics, an avalanche diode is a diode (made from silicon or other semiconductor) that is designed to experience avalanche breakdown at a specified reverse bias voltage. This feature provides better surge protection than a simple Zener diode and acts more like a gas discharge tube replacement.
Which method is used in avalanche photodiode?
Indium Phosphide (InP) is widely used as the multiplication layer material in commercially available APDs for applications in the 0.9–1.7µm wavelength region with In0.53Ga0.47As grown lattice-matched to it as the absorption layer.
How big is a Geiger mode avalanche photodiode?
Radiation Monitor Devices Inc. (RMD) developed an array of APDs with single photon detection capability for DIRC applications (Detection of Internally Reflected Cherenkov light). It consists of 6×14 individual APDs with a size of 150×150 μm 2. It is operated in Geiger-mode and has an active quenching circuit for each APD [7].
What kind of electronic device is avalanche photodiode?
Avalanche photodiode. An avalanche photodiode (APD) is a highly sensitive semiconductor electronic device that exploits the photoelectric effect to convert light to electricity.
How does a Geiger mode APD array work?
Geiger-mode avalanche photodiode arrays overcome limitations of a single device, and can distinguish between multiple-photon and single-photon events. Geiger-mode avalanche photodiode arrays overcome limitations of a single device, and can distinguish between multiple-photon and single-photon events.
Which is the best description of Geiger mode detection?
• Single event detection is often referred to as Geiger-mode detection, a term derived from X-rays • A Geiger-mode detector (GmD) emits a macroscopic current from the detection of a single photon • Used with a clock, a GmD is ideal for detection and Time-of-Flight (TOF) ranging applications What is Geiger-mode (Gm) detection?
