美空军的研究发现,采用以光纤代替电线载运信号的光子器件,尽管有抗电磁干扰(EMI)的名声,仍易受EMI的损害,因而在军用中通常需要屏蔽。EMI可通过调制光束或执行其他功能的电子器件进入系统。研究人员试验了若干光子器件,包括电光、 The U.S. Air Force study found that photonic devices that use optical fiber instead of wire-carrying signals are often shielded in military applications despite their reputation for electromagnetic interference (EMI), which is still subject to EMI damage. EMI can enter the system by modulating light beams or by performing other functions of the electronics. Researchers tested several photonic devices, including electro-optic,
