4H–SiC Avalanche Photodiode Linear Array Operating in Geiger Mode

open access: yesIEEE Photonics Journal, 2017
In this study, a 50-pixel linear array of 4H–SiC ultraviolet avalanche photodiodes operating in Geiger mode is reported for the first time. The 50 pixels within the linear array are all capable of detecting single photons but with a small number ...

Low-Noise and High-Efficiency Near-IR SPADs in 110nm CIS Technology [PDF]

open access: yes, 2019
Photon detection at longer wavelengths is much desired for LiDAR applications. Silicon photodiodes with deeper junctions and larger multiplication regions are in principle more sensitive to near-IR photons.

Timing performance of 30-nm-wide superconducting nanowire avalanche photodetectors [PDF]

open access: yes, 2011
We investigated the timing jitter of superconducting nanowire avalanche photodetectors (SNAPs, also referred to as cascade switching superconducting single photon detectors) based on 30-nm-wide nanowires. At bias currents (IB) near the switching current,

Characterisation Studies of Silicon Photomultipliers

open access: yes, 2010
This paper describes an experimental setup that has been developed to measure and characterise properties of Silicon Photomultipliers (SiPM). The measured SiPM properties are of general interest for a multitude of potential applications and comprise the ...

Effect of impact ionization in the InGaAs absorber on excess noise of avalanche photodiodes [PDF]

open access: yes, 2005
The effects of impact ionization in the InGaAs absorption layer on the multiplication, excess noise and breakdown voltage are modeled for avalanche photodiodes (APDs), both with InP and with InAlAs multiplication regions.

Characteristics Measurement in a Deep UV Single Photon Detector Based on a TE-cooled 4H-SiC APD

open access: yesIEEE Photonics Journal, 2023
We report on the characteristics of a lab-assembled UV single photon detector based on a thermoelectrically cooled silicon carbide (4H-SiC) avalanche photodiode (APD).

An avalanche-photodiode-based photon-number-resolving detector

open access: yes, 2008
Avalanche photodiodes are widely used as practical detectors of single photons.1 Although conventional devices respond to one or more photons, they cannot resolve the number in the incident pulse or short time interval.

Effect of dead space on avalanche speed [PDF]

open access: yes, 2002
The effects of dead space (the minimum distance travelled by a carrier before acquiring enough energy to impact ionize) on the current impulse response and bandwidth of an avalanche multiplication process are obtained from a numerical model that ...

Bit Error Rates for Ultrafast APD Based Optical Receivers: Exact and Large Deviation Based Asymptotic Approaches [PDF]

open access: yes, 2009
Exact analysis as well as asymptotic analysis, based on large-deviation theory (LDT), are developed to compute the bit-error rate (BER) for ultrafast avalanche-photodiode (APD) based optical receivers assuming on-off keying and direct detection.

An integral gated mode single photon detector at telecom wavelengths

open access: yes, 2007
We demonstrate an integral gated mode single photon detector at telecom wavelengths. The charge number of an avalanche pulse rather than the peak current is monitored for single-photon detection.
