混合量子信息协议基于局部量子比特，如被困原子、NV中心和量子点，与光子耦合。耦合是通过光学腔实现的。在这里，我们展示了远场优化的H1光子晶体膜腔与膜下附加的背反射镜相结合，满足实现混合量子信息协议的光学要求。通过数值优化，我们发现在0.8的物镜数值孔径内，80%的光可以被辐射出去，并且与单模光纤的耦合可以高达92%。我们通过谐振反射光谱实验证明了其独特的外模匹配特性，腔模可见性在50%以上。(C) 2012美国光学学会
Hybrid quantum information protocols are based on local qubits, such as trapped atoms, NV centers, and quantum dots, coupled to photons. The coupling is achieved through optical cavities. Here we demonstrate far-field optimized H1 photonic crystal membrane cavities combined with an additional back reflection mirror below the membrane that meet the optical requirements for implementing hybrid quantum information protocols. Using numerical optimization we find that 80% of the light can be radiated within an objective numerical aperture of 0.8, and the coupling to a single-mode fiber can be as high as 92%. We experimentally prove the unique external mode matching properties by resonant reflection spectroscopy with a cavity mode visibility above 50%. (C) 2012 Optical Society of America
