Entangled photon-pair sources are used in a variety of applications including quantum computation, quantum cryptography, quantum communication, teleportation, quantum clock synchronization, and quantum imaging. Several approaches have been used for entangled photon generation in optical fibers based on phase-matched four-wave mixing (FWM). Phase-matching has been achieved by engineering (1) intermodal chromatic-dispersion in single-mode optical fibers such as dispersion-shifted fibers, microstructured fibers, and photonics crystal fibers, as well as (2) intramodal dispersion in multimode fiber waveguides such as birefringent optical fibers for polarization entangled photon generation. Novel efficient entangled photon sources can be achieved by engineering intramodal dispersion in fused micro-couplers due to their strong

纠缠光子对源可用于多种应用，包括量子计算、量子密码学、量子通信、隐形传态、量子时钟同步和量子成像。基于相位匹配四波混频 (FWM) 的光纤中已使用多种方法生成纠缠光子。相位匹配是通过设计（1）单模光纤（例如色散位移光纤、微结构光纤和光子晶体光纤）中的模间色散，以及（2）多模光纤波导（例如用于产生偏振纠缠光子的双折射光纤）中的模内色散来实现的。新型高效纠缠光子源可以通过在融合微耦合器中设计模内色散来实现，因为它们具有很强的
