What are Single Photon Avalanche Diodes (SPADs)?
SPADs, or Single Photon Avalanche Diodes, are highly sensitive semiconductor devices capable of detecting individual photons of light. Unlike traditional photodiodes, SPADs operate in a “Geiger mode,” triggering an avalanche current upon photon absorption. This allows for extremely precise timing measurements, crucial for applications like photon counting and time-of-flight ranging.

SPAD Technology: Core Principles
SPADs detect single photons via avalanche multiplication, offering exceptional timing resolution and quantum efficiency – crucial for precise photon counting applications.
Avalanche Multiplication Process
SPADs operate by utilizing a phenomenon known as avalanche multiplication. When a single photon strikes the semiconductor material within the SPAD, it generates an electron-hole pair. This initial charge carrier is then accelerated by a strong electric field.
As the accelerated carrier collides with other atoms, it creates additional electron-hole pairs, leading to an exponential increase in charge carriers – the ‘avalanche’. This process dramatically amplifies the initial signal from a single photon, making it detectable.
Crucially, this avalanche is quickly quenched, resetting the SPAD for the detection of subsequent photons. The efficiency of this process, and the speed of quenching, are key determinants of SPAD performance, impacting timing resolution and overall sensitivity.
Quantum Efficiency and SPAD Performance
Quantum efficiency (QE) is a critical metric for SPADs, representing the probability that an incident photon will generate a detectable avalanche event. Higher QE directly translates to improved sensitivity, allowing the detection of fainter signals.
Factors influencing QE include the SPAD material, its structure, and the wavelength of the incident light. InGaAs/InP SPADs, like those from Princeton Lightwave, are optimized for near-infrared wavelengths, exhibiting high QE in that spectral range.
