Abstract
An optical signal processor, capable of eliminating design change of lens optical systems, it is fabricating by selecting one or more optical waveguides, each having a mode field diameter such that a desired band width of the transmission characteristics of the whole optical signal processor with respect to the light beam are selected as the input and output optical waveguides. When one optical waveguide is selected, the selected optical waveguide is applied as a common optical waveguide corresponding to both input and output optical waveguides. When two optical waveguides are selected, one is applied to the input optical waveguide and the other is applied to the output optical waveguide.
