Optimized Spectral Purity of Heralded Single Photons at the Telecom O-Band
Wu-Hao Cai, Soyoung Baek, Rui-Bo Jin +1
We report on optimizing the spectral purity of heralded single photons in the telecom O-band, where single photons can be propagated with low loss and low dispersion in a standard…
Mid-infrared spectrally-pure single-photon states generation from 22 nonlinear optical crystals
Wu-Hao Cai, Ying Tian, Rui-Bo Jin
We theoretically investigate the preparation of pure-state single-photon source from 14 birefringent crystals (CMTC, THI, LiIO, AAS, HGS, CGA, TAS, AGS, AGSe, GaSe, LIS, LISe,…
Optimized design of the lithium niobate for spectrally-pure-state generation at MIR wavelengths using metaheuristic algorithm
Wu-Hao Cai, Ying Tian, Shun Wang +3
Quantum light sources in the mid-infrared (MIR) band play an important role in many applications, such as quantum sensing, quantum imaging, and quantum communication. However, ther…
Broadband-laser-diode pumped PPKTP-Sagnac polarization-entangled photon source
Neng Cai, Wu-Hao Cai, Shun Wang +3
We experimentally demonstrate a polarization-entangled photon source at 810 nm using a type-II phase-matched PPKTP crystal pumped by a low-cost, broadband laser diode with a centra…
Mid-infrared spectrally-uncorrelated biphotons generation from doped PPLN: a theoretical investigation
Bei Wei, Wu-Hao Cai, Chunling Ding +4
We theoretically investigate the preparation of mid-infrared (MIR) spectrally-uncorrelated biphotons from a spontaneous parametric down-conversion process using doped LN crystals,…
Counter-propagating spectrally uncorrelated biphotons at 1550 nm generated from periodically poled MTiOXO4 (M = K, Rb, Cs; X = P, As)
Wu-Hao Cai, Bei Wei, Shun Wang +1
We theoretically investigated spectrally uncorrelated biphotons generated in a counter-propagating spontaneous parametric downconversion (CP-SPDC) from periodically poled MTiOXO4 (…
Spectrally uncorrelated biphotons generated from `the family of BBO crystal'
Rui-Bo Jin, Wu-Hao Cai, Chunling Ding +4
Spectrally intrinsically uncorrelated biphoton states generated from nonlinear crystals are very important but rare resources for quantum photonics and quantum information applicat…
