我们报道了一个由广泛非简并腔增强自发下转换产生的超窄带光子对源。该源被设计为与Pr3+固态量子存储器和电信光纤兼容，信号和空闲光子分别接近606 nm和1436 nm。两个光子的光谱带宽都在2 MHz左右，与掺杂Pr3+的量子存储器的带宽相匹配。该源非常适合涉及固态量子存储器的长距离量子通信架构。
We report on a source of ultranarrow-band photon pairs generated by widely nondegenerate cavity-enhanced spontaneous down-conversion. The source is designed to be compatible with Pr3+ solid state quantum memories and telecommunication optical fibers, with signal and idler photons close to 606 nm and 1436 nm, respectively. Both photons have a spectral bandwidth around 2 MHz, matching the bandwidth of Pr3+ doped quantum memories. This source is ideally suited for long distance quantum communication architectures involving solid state quantum memories.
