介绍了光功率分配器的结构、整体形状、技术指标要求,以及近年来发展起来的新型光功率分配器。对光功率分配器的关键技术———离子交换法制作光功率分配进行了详细的分析。结果表明,生产玻璃波导光功率分配器的设备和工艺相对其它方法(如LiNbO3光刻蚀法)要简单,一次性的固定投入较少,是生产光功率分配器的理想选择。 The structure, overall shape and technical requirements of optical power splitter are introduced, and the new optical power splitter developed in recent years is introduced. The key technology of optical power splitter --- ion exchange method of making optical power distribution were analyzed in detail. The results show that the production of glass waveguide optical power splitter device and process relative to other methods (such as LiNbO3 photolithography) to be simple, less fixed one-time investment, is the ideal choice for the production of optical power splitter.
