提出了在两块单光子光折变晶体和一个电源通过导线串联而成的回路中存在灰-灰屏蔽光伏空间孤子对的理论。在适当的条件下,推出了在晶体回路中两光束传播的耦合方程。证明了灰-灰独立屏蔽光伏孤子对的存在。研究结果表明,孤子对中的两灰孤子通过光诱导电流而相互影响,它们的相互耦合能影响到彼此的空间包络、动态演化和稳定性。
为了研究海洋湍流对单光子捕获概率的影响,基于模厄米高斯光束和Nikishov海洋湍流模型,根据Rytov近似和Kolmogorov谱,推导出了海洋湍流环境下的单光子捕获概率模型,并对不同海洋湍流参数对单光子捕获概率的影响进行了分析。结果表明:在传播百米后,海洋湍流环境下的单光子捕获概率下降明显;随着温度方差耗散率的增大,单光子捕获概率降低;当盐度因素主导海洋湍流时,单光子捕获概率也随盐度的增大而降低,盐度变化对海洋湍流环境下的单光子捕获概率的影响显著。增大接收机孔径值与缩短脉冲间隔可以有效提升单光子捕获概
In the past decade, lead halide perovskites have emerged as potential optoelectronic materials in the fields of light-emitting diode, solar cell, photodetector, and laser, due to their low-cost synthesis method, tunable bandgap, high quantum yield, large
