论文摘要
电频梳被用来迅速询问光机电传感器，证明光谱分辨率实质上超过了模式锁定的频率梳子。使用基于集成电路的直接数字合成器生成频率梳子，并用于自生态配置。与基于激光锁定或扫描的方法不同，目前的方法可以快速，平行测量完整的光腔模式，大型动态传感器位移范围以及在DC和500 kHz之间的较大频率范围内的习得。除了非常适合测量腔光力传感器的测量外，这种基于光频率梳子的方法还可以用于在广泛的物理和化学传感器中进行询问。
Electro-optic frequency combs were employed to rapidly interrogate an optomechanical sensor, demonstrating spectral resolution substantially exceeding that possible with a mode-locked frequency comb. Frequency combs were generated using an integrated-circuit-based direct digital synthesizer and utilized in a self-heterodyne configuration. Unlike approaches based upon laser locking or sweeping, the present approach allows rapid, parallel measurements of full optical cavity modes, large dynamic range of sensor displacement, and acquisition across a wide frequency range between DC and 500 kHz. In addition to being well suited to measurements of cavity optomechanical sensors, this optical frequency comb-based approach can be utilized for interrogation in a wide range of physical and chemical sensors.
