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,…
Identification of diffracted vortex beams at different propagation distances using deep learning
Heng Lv, Yan Guo, Zi-Xiang Yang +4
Orbital angular momentum of light is regarded as a valuable resource in quantum technology, especially in quantum communication and quantum sensing and ranging. However, the OAM st…
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…
