Abstract(in English) The temperature dependence of optical filters is a serious problem for the dense WDM systems. This dependence is owing to the temperature dependence of optical path-length of the waveguide. In this study, we realized a temperature independent silica-based optical filter at 1.55μm wavelength using an athermal waveguide in which optical pathlength is independent of temperature. First, we designed a silica-based athermal waveguide with square core cross section. Next, using the designed value, we desigened and fabricated a ring resonator. As a result, we successfully decreased the temperature dependense of central wavelength to 3% and 0.3% of corresponding values of silica and semiconductor waveguide filters, respectively.
