论文摘要
与时间相关的光子对是由三波谐音的四波混合在$ _ {0.5} $ ga $ _ {0.5} $ p光子晶体cavitiy产生的。通过积极补偿腔模式的残余光谱未对准来达到最大效率。在Q因子$ \ 4 \ times 10^4 $的腔中，发电率达到5 MHz，比使用带有相似Q因子在同一芯片上制造的相似Q因子的环谐振器测量的数量级以上。光子晶体源集成在SI光子电路上，这是量子技术应用的重要资产。
Time-correlated photon pairs are generated by triply-resonant Four-Wave-Mixing in a In$_{0.5}$Ga$_{0.5}$P Photonic Crystal cavitiy. Maximal efficiency is reached by actively compensating the residual spectral misalignment of the cavity modes. The generation rate reaches 5 MHz in cavities with Q-factor $\approx 4\times 10^4$, more than one order of magnitude larger than what is measured using ring resonators with similar Q factors fabricated on the same chip. The Photonic Crystal source is integrated on a Si photonic circuit, an important asset for applications in quantum technologies.
