نویسندگان
چکیده
We present the design and characterization of a microelectronic chip consisting 32 independent single-photon counting multi-photon time-coincidence channels, based on Single Photon Avalanche Diodes (SPADs). The aims at easing assembly together with Silicon Photonics substrates chips, for broad spectrum quantum applications. provides not only pulse outputs multi-channel counting, but it features other two operation modalities. For applications, single-hit digital address channel detecting photon among ones. an event-driven every time more than n photons (n selectable between 2 4) concurrently trigger different channels. Each detection consists 4 SPADs diameter (5 μm, 10 20 50 μm), to easily match waveguides collection efficiency.

Distortions from Multi-photon Triggering in a Single CMOS SPAD
Motivated by the need for correct characterization and operation of single-photon avalanche diodes (SPADs), three methods for discriminating between singleand multi-photon triggering in a single CMOS SPAD are compared. The first method, utilizing a measurement of the avalanche’s quench time, correctly distinguishes between avalanches initiated by one photon or 100 incident photons with p > 0.80...
متن کاملAdvantages of Silicon Photonics for Multi-socket Systems
Future single-board multi-socket systems may be unable to deliver the needed memory bandwidth electrically due to power limitations, which will hurt their ability to drive performance improvements. Energy efficient off-chip silicon photonics could be used to deliver the needed bandwidth, and it could be extended on-chip to create a relatively flat network topology. That flat network may make it...
متن کامل1 Photon coincidence spectroscopy for multi – atom cavity quantum electrodynamics
We show that photon coincidence spectroscopy can provide an un-ambiguous signature of two atoms simultaneously interacting with a quantised cavity field mode. We also show that the single–atom Jaynes–Cummings model can be probed effectively via photon coincidence spectroscopy, even with deleterious contributions to the signal from two–atom events. In addition, we have explicitly solved the eige...
متن کاملSilicon-chip source of bright photon pairs.
Integrated quantum photonics relies critically on the purity, scalability, integrability, and flexibility of a photon source to support diverse quantum functionalities on a single chip. Here we report a chip-scale photon-pair source on the silicon-on-insulator platform that utilizes dramatic cavity-enhanced four-wave mixing in a high-Q silicon microdisk resonator. The device is able to produce ...
متن کاملPhoton Detection with Silicon Photomultipliers
The Silicon Photomultiplier (SPM) addresses the challenge of detecting, timing and quantifying low-light signals down to the single-photon level. Traditionally the province of the Photomultiplier Tube (PMT), Avalanche Photodiode (APD), or PIN photodiode with high-gain amplifier, the Silicon Photomultiplier now offers a highly attractive alternative that closely mimics the low light detection ca...
