摘要：

A novel ultra-compact triplexer is designed by basing it on a combination of a 2 x 2 generalized interference-multimode interference (Gl-MMl) coupler. The MMl is formed into linear butterfly shape and a directional coupler using silicon rib waveguides. Firstly, the 2 x 2 MMl coupler is designed to separate the wavelength 1490 nm into one port and wavelengths of 1310 nm and 1550 nm into another port. Then a directional coupler is used to drop wavelengths of 1310 nm and 1550 nm to output ports individually. Numerical simulations with three-dimensional Beam Propagation Method (BPM) are utilized to design and optimize the operation of the proposed triplexer. (c) 2013 Elsevier B.V. All rights reserved.
