Absolute Measurement of Quantum Efficiency Based on Parametric Down-conversion Effect

Abstract

A new radiometric method which employs quantum properties of radiation and does not require the use of standard radiation sources and receivers has been suggested. This method uses the process of three-photon down conversion in non-central-symmetrical media to measure the quantum efficiency of photodetectors.

Absolute meter of photodetector quantum efficiency based on the parametric down-conversion effect

Vera M. Ginzburg, N. G. Keratishvili, Y. L. Korzhenevich +3 more

The quantum phenomena of parametric down conversion have been used for absolute measurement of the photodetector quantum efficiency of ultra-low-light radiation ranging from 10-12 to 10-15 W, which is equivalent to photon fluxes of 107 to 104 s-1. The process of parametric down conversion gives rise to highly correlated (in time and space) photon flux pairs. We describe the method, experimental investigation, and a new device involving the measurement of the coincidence rate of photodetection of these two correlated beams of light. The coincidence is lowered by a nonunit quantum efficiency of either detection. This fact was used for the definition of the absolute value of both photodetector's quantum efficiencies.

Measurement of quantum efficiency of avalanche photodetectors based on quantum two-photon field

A. Czitrovszky, Alexander V. Sergienko

A pair of rigorously correlated photons (biphotons) from parametric down conversion makes it possible to use them for measuring the absolute value of the quantum efficiency of the optical detectors, both in photon counting and in analog regimes, that does not use any calibrated standard light sources. Using this method the quantum efficiency of EG&G avalanche photodetectors was determined.

Absolute self-calibration of single-photon detectors with cw and pulsed spontaneous parametric down-conversion

Single-photon detectors are of great importance in spectroscopy, laser ranging, astronomy and wherever weak light detection is required, so a precise knowledge of their quantum efficiency is essential, but their calibration is by no means trivial. Traditional methods need a black body radiation source or a highly attenuated laser beam as a reference standard, or an already calibrated reference detector. It is well known that absolute measurement of the quantum efficiency, absolute in the sense that the calibration is independent of any radiometric standard or the properties of another detector, can be performed using entangled twin photons generated in optical spontaneous parametric down-conversion together with a reference detector. We have performed the first proof-of-principle experiment to determine the quantum efficiency by which no second detector or reference standard is required. This absolute self-calibration method is also based on the time correlation of photons emitted in parametric down-conversion, but with the introduction of a suitable time delay between the arrival times of the twin photons. Furthermore, we describe a scheme for absolute self-calibration of the quantum efficiency at different wavelengths by means of a pulsed source of nondegenerate down-converted photons. This method should have even greater potential for applications.

Investigation of absolute measurement in quantum efficiency of photoelectric detectors by means of correlated photons

Yu Feng, Xiaobing Zheng, Yanli Qiao +1 more

There are two general methods for radiometric calibration of detectors. One is based on radiometric sources and the other is based on detectors. Because two methods need to establish primary standard of high precision and transfer chain of standard, the precision of standard will be reduced by extension of the chain. An absolute calibration of quantum efficiency of detectors can be realized by using correlated photons generated in spontaneous parametric down-conversion (SPDC) effect of nonlinear crystal. Generation mechanism of SPDC is interpreted with theories of quantum mechanics and classical theories. The theory of calibration based correlated photons are demonstrated. The project for proof of principle of absolute calibration of quantum efficiency of radiometric detectors is given in this paper. Comparing with traditional methods, the advantages of it are pointed out. A scheme using to calibrate quantum efficiency of infrared detectors is described here. The measurement of spatial and spectral response of detectors is mentioned too.
