Aaron C. Hryciw, Marcelo Wu, Behzad Khanaliloo, Paul E. Barclay

摘要:

利用可调谐倏逝波耦合来改变分束光子晶体纳米腔中的光机械相互作用。一个光纤锥形探针被用来重新归一化的光学纳米腔场,并引入一个耗散光机械耦合通道,重新配置和增强设备的光学和机械谐振之间的耦合。光纤锥的定位允许优先耦合到特定的机械模式,并提供了一种用于调谐耗散和色散耦合机制之间的光机械相互作用的机制。

英文摘要:

Tunable evanescent coupling is used to modify the optomechanical interactions within a split-beam photonic crystal nanocavity. An optical fiber taper probe is used to renormalize the optical nanocavity field and introduce a dissipative optomechanical coupling channel, reconfiguring and enhancing coupling between the optical and mechanical resonances of the device. Positioning of the fiber taper allows preferential coupling to specific mechanical modes and provides a mechanism for tuning the optomechanical interaction between dissipative and dispersive coupling regimes.
