Characterization of a Geiger-mode Avalanche Photodiode
A 32 by 32 array of packaged 100 μm Geiger-mode avalanche photodiodes were tested and characterized. A breakdown voltage of 32 V was measured; at or just above this voltage is where the device should be biased in order to operate in Geiger-mode. The ideal region of the forward biased IV curve resulted in an ideality factor of 1.0 and no recombination/generation region. In addition, IDL code was...
متن کاملThe Blocking Probability of Geiger-Mode Avalanche Photo-diodes
When a photon is detected by a Geiger-mode avalanche photo-diode (GMAPD), the detector is rendered inactive, or blocked, for a certain period of time. In this paper we derive the blocking probability for a GMAPD whose input is either an unmodulated, Bernoulli modulated or pulse-position-modulated (PPM) Poisson process. We demonstrate how the PPM and Bernoulli cases differ, illustrating that the...
متن کاملSimulation of Dark Count in Geiger Mode Avalanche Photodiodes
Silicon avalanche photodiodes operated above breakdown, in Geiger mode, can be sensitive enough to allow single photon detection. An inherent limit to GMAPD sensitivity is the noise caused by thermally generated carriers. This noise manifests itself as extraneous counts in the absence of light and is termed the dark count. The presence of the dark count in GM-APD detectors reduces the signal to...
متن کاملAn ultrafast Geiger-mode single photon avalanche diode in 0.18 m CMOS technology
We demonstrate a new single-photon avalanche diode (SPAD) device, which utilizes the silicon-dioxide shallow-trench isolation (STI) structure common to all deep-submicron CMOS technologies, both for junction planarization and as an area-efficient guard-ring. This makes it possible to achieve an order-of-magnitude improvement in fill factor and a significant reduction in pixel area compared with...
متن کاملCharacterisation of Geiger-mode avalanche photodiodes for medical imaging applications
Recently developed multipixel Geiger-mode avalanche photodiodes (G-APDs) are very promising candidates for the detection of light in medical imaging instruments (e.g. positron emission tomography) as well as in high-energy physics experiments and astrophysical applications. G-APDs are especially well suited for morpho-functional imaging (multimodality PET/CT, SPECT/CT, PET/MRI, SPECT/MRI). G-AP...
