In this paper, we introduce a new two mode division (de) multiplexer with optical properties of broad bandwidth, high mode conversion efficiency that is built on silicon-on-insulator (SOI) platform. By using an asymmetric directional coupler in the form of an MZI structure, mode (de)multiplexer from the fundamental mode TE0 and the firstorder mode TE1 can be achieved by numerically analysis. Performance...
A novel ultra-compact triplexer is designed by basing it on a combination of a 2×2 generalized interference-multimode interference (GI-MMI) coupler. The MMI is formed into linear butterfly shape and a directional coupler using silicon rib waveguides. Firstly, the 2×2 MMI coupler is designed to separate the wavelength 1490nm into one port and wavelengths of 1310nm and 1550nm into another port. Then...
