Based on the transformation optics, a general method of light-behavior remote control is proposed. From this method, the important coefficients of a cavity, i.e. the quality factor Q and the resonant frequency ?0 could be tuned in a wide range by a transformation optical device in distance, so that the light behavior can be remotely controlled. To confirm this original idea, three schemes, such as, the remote modification of output energy current from an absorptive cavity, the remote control of lasing behaviors, and the remote tuning of the resonant frequency or photonic band-gap, are presented and confirmed by our numerical simulations based on finite-difference time-domain and finite-element methods. With some special advantages, e.g., without physical change or damage of original devices, large tuning range, and easily to hide the controller, this method could be widely used in optical/photonic or electromagnetic designs in the future.
基于变换光学原理，提出了一种光行为远程控制的通用方法。通过该方法，利用变换光学器件在一定距离外可对腔的重要系数，即品质因数Q和谐振频率ω0进行大范围调谐，从而实现对光行为的远程控制。为验证这一原创想法，提出了三种方案，如对吸收腔输出能量电流的远程修改、激光行为的远程控制以及谐振频率或光子带隙的远程调谐，并通过基于时域有限差分法和有限元法的数值模拟得到了验证。该方法具有一些特殊优势，如不改变或损坏原始器件的物理状态、调谐范围大且易于隐藏控制器，未来可广泛应用于光学/光子或电磁设计中。
