摘　　要：电磁波通信在无线大气通信中应用广泛,由于电磁波在海水传输过程中衰减很大而应用受到限制,当发现蓝绿激光在海水中传输存在低损耗特性后,可以使蓝绿激光在水下通信中得到广泛应用。利用光子晶体的光子禁带和光子局域的特性制作的一维光子晶体窄带滤光器,能够用于蓝绿激光水下对潜通信系统的接收端,几乎能够完全抑制在海水传输中低损耗窗口外的背景光和干扰光,有利于提高系统信噪比。The technology of electromagnetic wave communications is applied widely in wireless communications, However, its applications are limited in underwater communications due to water attenuation. It is applied in the underwater communications after the ＂blue-green window＂ was covered. A narrow filter produced by photonic band gap and photon localization of photonic crystal is introduced in this paper, It is designed for the use in the receiver of the submarine blue-green laser communication system. The background light and interference light can be inhibited in the low-loss-window. And the SNR of the system is thus raised.
