| Abstract(in English) | A new grid-free WDM system has been proposed in order to overcome the problems of conventional WDM systems that are subject to the necessity of temperature control and the limitation of wavelength spacing. Since the new system requires multi-wavelength lasers with the same wavelength spacing, this time, for the preparation of 1.3 μm band multi-wavelength lasers using SiN waveguides, the refractive index analysis of SiN by changing the film formation conditions and the changes of chromatic dispersion and propagation mode by changing waveguide structure were investigated. In the refractive index analysis, a change of about 0.05 was obtained in the 1.3 μm band by changing the conditions. In the calculation of chromatic dispersion and propagation mode, we confirmed the dispersion shift due to the film forming conditions, and confirmed the value near zero chromatic dispersion at the waveguide cross-sectional area of 0.54 μm2. |
