论文摘要
光子学中的下一个前沿将依赖于不同材料系统的协同组合。一个独特的有机分子是偶氮苯。当在蓝色（反式向上）或中ir（顺式对频率）中光学激发时，该分子可以可逆地改变构象。在这里，我们演示了用含氮偶合的4-（4-二甲基氨基苯基唑）吡啶（Aazo）的单层修饰的SiO2光谐振器（Aazo），其质量因子超过106。使用一对激光器，分子在分子构象之间被逆转，在分子构象之间旋转，并散发出频率的变化，并逐渐变形。偏移量表与Aazo的相对表面密度。实验数据与理论建模一致。
The next frontier in photonics will rely on the synergistic combination of disparate material systems. One unique organic molecule is azobenzene. This molecule can reversibly change conformations when optically excited in the blue (trans-to-cis) or mid-IR (cis-to-trans). Here, we demonstrate SiO2 optical resonators modified with a monolayer of azobenzene-containing 4-(4-diethylaminophenylazo)pyridine (Aazo) with quality factors over 106. Using a pair of lasers, the molecule is reversibly flipped between molecular conformations, inducing resonant wavelength shifts, and multiple switching cycles are demonstrated. The magnitude of the shift scales with the relative surface density of Aazo. The experimental data agrees with theoretical modeling.
