利用微致动器对光子晶体板中光的传输和局域化特性进行了数值和实验研究。微机械致动器控制外部结构元件的位置，该外部结构元件位于靠近PhC板的位置，并且通过改变限制在PhC板中的光与外部元件的倏逝相互作用来调制PhC特性。当外部结构元件接近线缺陷PhC波导时，发生强度和相位调制。在初步的实验中，我们利用线缺陷的PhC波导，在1.55 μm波长处实现了消光比约10 dB的光开关操作。光在点缺陷腔中的局域态也可以被控制。数值模拟了两个PhC片的组合在1.55 μm附近的~ 60 nm光谱范围内的谐振波长调谐。这里讨论的方法可以广泛地用于实现功能和可调谐的PhC平板器件。
The tuning of the light propagation and localization properties in photonic crystal (PhC) slabs by using microactuators was demonstrated numerically and experimentally. A micromechanical actuator controls the position of the exterior structural element, which is located close to the PhC slab, and modulates the PhC properties through the change of the evanescent interaction of light confined in the PhC slab with the exterior element. When the exterior structural element approaches to a line-defect PhC waveguide, intensity and phase modulations occur. In the preliminary experiment using a line-defect PhC waveguide, we demonstrated the optical switching operation with an extinction ratio of ~10 dB at a wavelength of 1.55 μm. The localized state of light in a point-defect cavity can also be controlled. The tuning of the resonant wavelength over the spectral range of ~60nm at around the wavelength of 1.55 μm was numerically demonstrated by combining two PhC slabs. The approach discussed here can be widely employed for realizing functional and tunable PhC slab devices.
