Abstract: | We propose and experimentally demonstrate a low-loss and low-crosstalk MachZehnder mode/wavelength multi/demultiplexer for WDM/MDM transmission based on a Siphotonics platform. A broadband 3-dB mode divider, which is also newly devised here, makes it possible to compose a Mach-Zehnder filter for "mode" and "wavelength" simultaneously. Transmission characteristics of fabricated 3-dB mode dividers are in excellent agreement with theoretical results. Mach-Zehnder filters using the 3-dB mode divider with a free spectral range (FSR) of 20 and 1 nm are also fabricated and the modal crosstalk is less than -24 dB in the 40-nm wavelength range for the MZ filter with an FSR of 20 nm. The tuning of the peak wavelength position by the TiN heater is also demonstrated. (C) 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement |
