Efficient generation of tunable photon pairs at 0.8 and 1.6 mm
نویسندگان
چکیده
We demonstrate efficient generation of collinearly propagating, highly nondegenerate photon pairs in a periodically poled lithium niobate cw parametric downconverter with an inferred pair generation rate of 1.4 3 107 s mW of pump power. Detection of an 800-nm signal photon triggers a thermoelectrically cooled 20%efficient InGaAs avalanche photodiode for the detection of the 1600-nm conjugate idler photon. Using single-mode fibers as spatial mode filters, we obtain a signal-conditioned idler-detection probability of 3.1%. © 2002 Optical Society of America OCIS codes: 270.0270, 030.5260, 190.4410, 270.5570.

We propose and experimentally demonstrate the generation of cross-polarized photon pairs via four-wave mixing with cross-polarized frequency-conjugate laser pump pulses. This method can be used for various quantum information applications such as the preparation of Bellstates. ©2005 Optical Society of America OCIS codes: (060.4370) Nonlinear optics, fibers; (190.4380) Nonlinear optics, four wav...
متن کاملHigh yield and ultrafast sources of electrically triggered entangled-photon pairs based on strain-tunable quantum dots
Triggered sources of entangled photon pairs are key components in most quantum communication protocols. For practical quantum applications, electrical triggering would allow the realization of compact and deterministic sources of entangled photons. Entangled-light-emitting-diodes based on semiconductor quantum dots are among the most promising sources that can potentially address this task. How...
متن کاملThe Impact of the Spectral Filter Bandwidth on the Spectral Entanglement and Indistinguishability of Photon Pairs of SPDC Process
In this paper, we have investigated the dependence of the spectral entanglement and indistinguishability of photon pairs produced by the spontaneous parametric down-conversion (SPDC) procedure on the bandwidth of spectral filters used in the detection setup. The SPDC is a three-wave mixing process which occurs in a nonlinear crystal and generates entangled photon pairs and utilizes as one of th...

In this paper, we numerically simulated a glass-based all-optical 1×N power splitter with eleven different configurations using soliton breakup in a nonlinear medium. It is shown that in addition to reconfigurability of the proposed splitter, its power splitting ratio is tunable up to some extent values too. Nonlinear semivectorial iterative finite difference beam propagation method (IFD-...
متن کاملSmall photon field dosimetry using EBT2 Gafchromic film and Monte Carlo simulation
Background: Small photon fields are increasingly used in modern radiotherapy especially in intensity modulated radiation therapy (IMRT) and stereotactic radiosurgery (SRS) treatments. Accurate beam profile and central axis depth doses measurements of such beams are complicated due to the electron disequilibrium. Hence the EBT2 (external beam therapy) Gafchromic film was used for dosimetry of sm...
