We propose and analyze a scheme to enhance optomechanically-induced-transparency (OMIT) based on parity-time-symmetric optomechanical system. Our results predict that an OMIT window which does not exist originally can appear in weak optomechanical coupling and driving system via coupling an auxiliary active cavity with optical gain. This phenomenon is quite different from these reported in previous works in which the gain is considered just to damage OMIT phenomenon even leads to electromagnetically induced absorption or inverted-OMIT. Such enhanced OMIT effects are ascribed to the additional gain which can increase photon number in cavity without reducing effective decay. We also discuss the scheme feasibility by analyzing recent experiment parameters. Our work provide a promising platform for the coherent manipulation and slow light operation, which has potential applications for quantum information processing and quantum optical device.
我们提出并分析了一种基于宇称-时间对称光机械系统增强光机械诱导透明（OMIT）的方案。我们的结果预测，通过将具有光学增益的辅助有源腔耦合到弱光机械耦合和驱动系统中，原本不存在的OMIT窗口可能会出现。这种现象与先前工作中报道的情况有很大不同，在先前工作中，增益被认为只会破坏OMIT现象，甚至会导致电磁诱导吸收或反演OMIT。这种增强的OMIT效应归因于额外的增益，它可以在不降低有效衰减的情况下增加腔内光子数。我们还通过分析近期实验参数来讨论该方案的可行性。我们的工作为相干操纵和慢光操作提供了一个有前景的平台，在量子信息处理和量子光学器件方面具有潜在应用。
