DOI: 10.1016/j.optcom.2016.07.028

Abstract: Abstract Photon modes have an important role in characterizing the quantum sources of light. The two main pre-detection factors affecting the biphoton mode coupling in SPDC are the pump beam focusing parameter and the crystal… read more here.

DOI: 10.1080/09500340.2017.1393568

Abstract: Abstract We investigate theoretically the strong anisotropy in the wave packet distribution of biphoton pairs generated via spontaneous parametric down-conversion (SPDC) process with biaxial crystals. From the angle relationship in biaxial crystals, we deduce the… read more here.

DOI: 10.1103/physrevapplied.23.014076

Abstract: Broadband correlated photon pairs (biphotons) are valuable in quantum metrology, but current generation methods either involve complex nonlinear structures or lack sufficient bandwidth and brightness. In this work, we theoretically describe and experimentally demonstrate a… read more here.
