摘要：
An ultra-compact triplexer is designed by mean of the construction of generalized interference-multimode interference (GI-MMI) couplers. In order to reduce the device length these couplers are formed into linear butterfly shape. Firstly, a butterfly MMI coupler is designed to separate the wavelength 1,490 nm into one port and wavelengths 1,310 and 1,550 nm into an another port. Then another one is used to drop wavelengths of 1,310 and 1,550 nm to output ports individually. Numerical simulations with three-dimensional beam propagation method and effective index method are utilized to design and optimize the operation of the proposed triplexer.
