摘要:

我们已经开发了一个严格的量子模型的自发参量下转换的非线性一维光子带隙结构的基础上扩展到单色平面波的字段。该模型提供了所创建的光子对的双光子振幅。在连续和脉冲泵浦下,用双光子振幅测量了信号光场和闲频光场的光谱、时域强度分布以及Hong-Ou-Mandel干涉仪中的符合计数干涉图样。可以使用表征发射的下转换场的宽范围的参数。作为一个例子,由49层GAN/AlN组成的结构被分析为具有高效率的光子对的合适源。

英文摘要:

We have developed a rigorous quantum model of spontaneous parametric down-conversion in a nonlinear 1D photonic-band-gap structure based upon expansion of the field into monochromatic plane waves. The model provides a two-photon amplitude of a created photon pair. The spectra of the signal and idler fields, their intensity profiles in the time domain, as well as the coincidence-count interference pattern in a Hong-Ou-Mandel interferometer are determined both for cw and pulsed pumping regimes in terms of the two-photon amplitude. A broad range of parameters characterizing the emitted down-converted fields can be used. As an example, a structure composed of 49 layers of GaN/AlN is analyzed as a suitable source of photon pairs having high efficiency.
