Static and dynamic wavelength routing via the gradient optical force
摘要：
在这里，我们提出并证明了一种全光波长路由的方法，它使用的调谐机制的基础上，在一个专门设计的纳米光学机械系统的光学梯度力。由此产生的机械兼容的“蜘蛛网”谐振器实现了无缝波长路由的范围内的3000倍的固有通道宽度，与309 GHz/mW的调谐效率，小于200纳秒的开关时间，并在整个调谐范围内100%的通道质量保护。这些结果表明，辐射压力驱动的设备被用于各种光子学应用，如通道路由/开关，缓冲，色散补偿，脉冲捕获/释放，和广泛的可调谐激光器的潜力。
英文摘要：
Here we propose and demonstrate an all-optical wavelength-routing approach which uses a tuning mechanism based upon the optical gradient force in a specially-designed nano-optomechanical system. The resulting mechanically-compliant "spiderweb" resonantor realizes seamless wavelength routing over a range of 3000 times the intrinsic channel width, with a tuning efficiency of 309-GHz/mW, a switching time of less than 200-ns, and 100% channel-quality preservation over the entire tuning range. These results indicate the potential for radiation pressure actuated devices to be used in a variety of photonics applications, such as channel routing/switching, buffering, dispersion compensation, pulse trapping/release, and widely tunable lasers.
