| Research Abstract |
In this research, the developments of the solitonic technology and the optical waveguide technology are aimed.
Specially, the application to the optical communication and to the fiber-optic sensors are intended. The application of the fiber-optic nonlinearity to the dispersion compensation, the wavelength-division-multiplex system and the novel digital soliton system are considered. The fundamental problems of the optical waveguide material, especially the photorefractive effect and the photoelectric effect are experimentally analyzed.
1. The photorefractive effect and the photoelectric effect of the lithium niobate crystal are experimentally investigated concerning the effect of the impurity and the annealing process.
2. The multiplex-demultiplexer for the wavelength-division multiplex system by using the consept of the arrayed waveguide utilizing the lithium niobate crystal are theoretically optimized and designed.
3. The dispersion management system of the soliton transmission is numerically analyzed.
4. The wavelength-division-multiplex system by the soliton is discussed numerically.
5. The generalized digital soliton system is proposed and numerically analyzed.
