A method of manufacturing an optical filter is a method of manufacturing an optical filter including two or more waveguides having four or more sections in which a number of modes of light propagating through the four or more sections is two or more. The method includes designing lengths of the four or more sections, and forming the two or more waveguides based on the lengths of the four or more sections. The designing includes designing the lengths of the four or more sections based on differentiation of propagation constants of the sections with respect to a temperature and widths of the sections.
A method of manufacturing an optical filter, the optical filter including two or more waveguides, the two or more waveguides having four or more sections, a number of modes of light propagating through the four or more sections being two or more, the method comprising:
A method of designing an optical filter, the optical filter including two or more waveguides, the two or more waveguides having four or more sections, a number of modes of light propagating through the four or more sections being two or more, the method comprising:
A design apparatus for designing an optical filter, the optical filter including two or more waveguides, the two or more waveguides having four or more sections, a number of modes of light propagating through the four or more sections being two or more, the design apparatus comprising:
