The first disadvantage of MMI device is wavelength sensitive, which leads to restricted applications. To reduce the wavelength insensitivity in optical network applications, the demand of light source with a specific wavelength is needed, especially for power splitters. For this reason, a wideband criterion for MMI splitter is proposed. The basic principle is based on reducing the interference length difference and making it shorter than the spot size for constructive mode interference. Simulation results show the spectra of proposed MMI splitter is wide enough (1.26-1.61um) to cover the fiber communication band and the size of the splitter is more compact than that of the conventional MMI or Y-branch splitter.

多模干涉元件的第一个缺点为波长敏感，此缺点会限制其在实际上的用途；因元件在网路上的应用时，通常都需要降低波长敏感性，以减低对光源波长准确性的要求；有鉴於此，本论文提出多模干涉分光器的宽频标准；基本原理是建立在缩短其多模干涉区的长度差，并使之小於建设性干涉的光点大小；透过模拟后发现，操作频宽可涵盖光纤通信全波段(1.26-1.61um)，且长度小於Y形分支结构的分光器。
