We report on reversible and continuously deformable soft micro-resonators and the control of their resonance split and directional emission. Assisted by computerized holographic-tweezers, functioning as an optical deformer of our device, we gradually deform the shape and change the functionality of a droplet whispering-gallery cavity. For example, we continuously deform hexagonal cavities to rectangular ones and demonstrate switching to directionally emitting mode-of-operation, or splitting a resonant mode to a 10-GHz separated doublet. A continuous trend of improving spatial light modulators and tweezers suggests that our method is scalable and can control the shape and functionality of many individual devices. We also demonstrate optional solidification, proving the feasibility of transformer-enabled applications, including in printing optical circuits and multiwavelength optical networks.

走向可转换的光子学：可逆变形软腔，控制它们的共振分裂和定向发射

我们报告了可逆和连续变形软微谐振器及其谐振分裂和定向发射的控制。在计算机全息镊子的帮助下，作为我们设备的光学变形器，我们逐渐变形形状并改变液滴回音壁腔的功能。例如，我们连续将六边形腔体变形为矩形腔体，并演示切换到定向发射操作模式，或将谐振模式拆分为 10 GHz 分离双峰。改进空间光调制器和镊子的持续趋势表明我们的方法是可扩展的，并且可以控制许多单个设备的形状和功能。我们还演示了可选的固化，证明了启用变压器的应用的可行性，
