摘要：

Combined use of wavelength division multiplexing (WDM) and mode division multiplexing (MDM) attracts a lot of attention for expanding transmission capacity. For WDM/MDM transmission, a broadband mode multi/demultiplexer (MUX/DEMUX) is necessary. In this work, we propose a silica-PLC-based Mach-Zehnder (MZ) interferometer mode MUX. The MZ filter for mode and wavelength is composed of bus and add waveguides, and it can be constructed by newly designed broadband 3dB-mode-divider. Furthermore, the size of the chip can be drastically reduced compared with that of silica-PLC by using Si/silica hybrid PLC platform (1/20), and the wavelength dependence of free-spectral range (FSR) is suppressed by using the platform with the bus-tapered waveguide, and Si/silica hybrid PLC platform in both of bus and add waveguides.
