Kind Code:

Abstract:

The optical waveguide-type wavelength dispersion compensation device of the present invention has an optical waveguide as a reflection-type wavelength dispersion compensation device. The equivalent refractive index of a core changes unevenly along a light propagation direction by changing physical dimensions of the core that is embedded in a cladding. The core is designed by (a) setting a first desired reflection spectrum, ignoring transmission losses of the optical waveguide, and designing an optical waveguide that is capable of compensating the wavelength dispersion of an optical fiber to be compensated; (b) deriving a wavelength dependency characteristic of a transmission loss amount of the optical waveguide from an effective length of the optical waveguide designed in process (a); and (c) adding a reverse dependency characteristic of the wavelength dependency characteristic to the first reflection spectrum to correct it to a second reflection spectrum, and redesigning an equivalent refractive index distribution of the optical waveguide designed in the process (a) by using this second reflection spectrum.
