N2 - Mode-division multiplexing (MDM) is widely researched, and we are researching mode converter by using multi-mode interference (MMI) waveguide. Wavelength division multiplexing (WDM) must be used in addition to the MDM, however, wavelength dependency exits for MMI in general as it works based on the interference of light. In this paper, we analyze the wavelength dependency of the MMI 0th to 1st mode-converter theoretically. As a result, we clarify the design scheme to suppress the wavelength dependency. Moreover, we show the sufficient performance of less than 1.0 dB in entire C-band for highly confined waveguide (Si/SiO2 waveguide) as a design example.
