摘要： PROBLEM TO BE SOLVED: To provide a photonic crystal optical waveguide element having a variable characteristic function by external electric field application and its manufacturing method, and a high-function device for optical communication which uses the element. SOLUTION: In the photonic crystal optical waveguide, liquid crystal and an electrode is introduced nearby a core in an area to be given variable characteristics and a refractive index that waveguide light senses is varied by changing the alignment direction of molecules of the liquid crystal forming a portion of an upper clad with an electric signal to control the propagation characteristic. The introduction of the liquid crystal is carried out by forming a hole of desired depth in a desired area by using an ion beam etc., and injecting the liquid crystal therein, or previously forming the upper clad thin and arranging the liquid crystal over the entire surface of the waveguide by using a spacer. Further, the device for optical communication such as a high-performance optical switch and a variable wavelength filter can be constituted by using electric field control over the Bragg blocking characteristic, wavelength dispersion characteristic, etc., of the waveguide.
