Efficient fiber-coupled single-photon source based on quantum dots in a photonic-crystal waveguide.
Many photonic quantum information processing applications would benefit from a high brightness, fiber-coupled source of triggered single photons. Here, we present a fiber-coupled photonic-crystal waveguide single-photon source relying on evanescent coupling of the light field from a tapered out-coupler to an optical fiber. A two-step approach is taken where the performance of the tapered out-co...

LLE Review, Volume 106 108 Practical quantum cryptography (QC) systems require ultrafast and high-quantum-efficiency (QE) single-photon detectors (SPD’s)1 with precise timing characteristics2 and sufficiently low dark counts. For fiber-optic QC systems, SPD’s working at the standard near-infrared (NIR) telecommunication wavelengths, namely 1.3 nm and/or 1.55 nm, with counting rates well above 1...
متن کاملAbsolute calibration of fiber-coupled single-photon detector.
We show a setup for characterising the efficiency of a single-photon-detector absolutely and with a precision better than 1%. Since the setup does not rely on calibrated devices and can be implemented with standard-optic components, it can be realised in any laboratory. Our approach is based on an Erbium-Doped-Fiber-Amplifier (EDFA) radiometer as a primary measurement standard for optical power...
متن کاملA Novel Stand-Alone Single-Phase Induction Generator Using a Three-Phase Machine and a Single-Phase PWM Inverter
A new type of single-phase stand-alone induction generator using a three-phase induction machine and a single-phase voltage-source PWM inverter is introduced. The generator scheme is capable of producing constant load frequency with a very well regulated output voltage. A small lead acid battery and a single-phase full diode-bridge rectifier are used to feed the inverter. The inverter feeds one...
متن کاملSingle Photon Source
Single photon sources are introduced as emitters which deliver one photon at one time. The necessity of developing single photon sources, related principles and the development of single photon sources are also discussed in this essay.
