In this Letter we demonstrate heralded single-photon generation in a III-V semiconductor photonic crystal platform through spontaneous four-wave mixing. We achieve a high brightness of 3.4×10(7) pairs·s(-1) nm(-1) W(-1) facilitated through dispersion engineering and the suppression of two-photon absorption in the gallium indium phosphide material. Photon pairs are generated with a coincidence-to-accidental ratio over 60 and a low g(2) (0) of 0.06 proving nonclassical operation in the single photon regime.
在这封信件中，我们通过自发四波混频演示了在 III-V 半导体光子晶体平台中的单光子产生。我们通过色散工程和抑制磷化镓铟材料中的双光子吸收实现了 3.4×10(7)对·s(-1)nm(-1)W(-1)的高光亮度。光子对的符合-偶然比超过 60，并且 g(2) (0) 低至 0.06，证明了在单光子态下的非经典操作。
