摘要:

研究了AlGaAs衬底上脊形波导形成的法布里-珀罗腔。实验测量了Rb原子波长780 nm处波导中的传输损耗。我们还对冷原子与腔场相互作用所引起的损耗进行了数值和解析估计。我们发现带隙腔的本征精细度可以达到F ~ 30的量级,当考虑到镜传输的损耗时,它对应于我们系统C ~ 1的协同性参数。

英文摘要:

We study a Fabry-Perot cavity formed from a ridge waveguide on a AlGaAs substrate. We experimentally determined the propagation losses in the waveguide at 780 nm, the wavelength of Rb atoms. We have also made a numerical and analytical estimate of the losses induced by the presence of the gap which would allow the interaction of cold atoms with the cavity field. We found that the intrinsic finesse of the gapped cavity can be on the order of F ~ 30, which, when one takes into account the losses due to mirror transmission, corresponds to a cooperativity parameter for our system C ~ 1.
