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 کاملA Geiger-mode avalanche photodiode array for X-ray photon correlation spectroscopy.
X-ray photon correlation spectroscopy (XPCS) provides an opportunity to study the dynamics of systems by measuring the temporal fluctuations in a far-field diffraction pattern. A two-dimensional detector system has been developed to investigate fluctuations in the frequency range of several Hz to kHz. The X-ray detector system consists of a thin 100 microm scintillation crystal coupled to a Gei...
متن کاملGeiger-Mode Avalanche Photodiode Arrays Integrated to All-Digital CMOS Circuits
This article reviews MIT Lincoln Laboratory's work over the past 20 years to develop photon-sensitive image sensors based on arrays of silicon Geiger-mode avalanche photodiodes. Integration of these detectors to all-digital CMOS readout circuits enable exquisitely sensitive solid-state imagers for lidar, wavefront sensing, and passive imaging.
متن کاملAnalysis and Modeling of Optical Crosstalk in InP-based Geiger-mode Avalanche Photodiode FPAs
Optical crosstalk is a major factor limiting the performance of Geiger-mode avalanche photodiode (GmAPD) focal plane arrays (FPAs). This is especially true for arrays with increased pixel density and broader spectral operation. We have performed extensive experimental and theoretical investigations on the crosstalk effects in InP-based GmAPD FPAs for both 1.06-μm and 1.55-μm applications. Mecha...
متن کاملSignal-to-noise ratio of Geiger-mode avalanche photodiode single-photon counting detectors
Geiger-mode avalanche photodiodes (GM-APDs) use the avalanche mechanism of semiconductors to amplify signals in individual pixels. With proper thresholding, a pixel will be either “on” (avalanching) or “off.” This discrete detection scheme eliminates read noise, which makes these devices capable of counting single photons. Using these detectors for imaging applications requires a well-developed...
