摘　　要：光反馈进入发光端后会对激光产生影响,缩短其寿命,并且会影响整个光通信系统的通信质量。光隔离器则是防止反馈光的有力器件。随着科学技术的不断进步,现在的光隔离器体积越做越小,性能越来越优良,而且成本也大幅降低,但仍没有十分完美的产品。如何将所有的优点整合到一起成为了今后光隔离器开发目标。论文重点介绍了微型宽带光隔离器的设计方法。The light＇s feedback will bring about infulence on the laser machine after getting the light source its life span, and influence the communication quality of the whole optical communication system. The isolator is a powerful apparatus to prevent the feedback light. With the continuously progress of scientific technology, the cubage of optical isolators nowadays are becoming smaller and smaller, the capability are becoming better and better, and the cost also advantages together becomes the target of devising optical isolator all the advantages together becomes the target of devising optical isolators in future. This essay emphasis on the introduction of methods of designing the wide potical isolator in miniature.
