Title: Wavelength conversion element and wavelength conversion device
Inventor: IKAMI MAKOTO
IPC: G02F1/355
Filed: 2001-10-26
Abstract: PROBLEM TO BE SOLVED: To obtain an entirely optical wavelength conversion element which uses a practicable nonlinear optical material and to provide a wavelength conversion device having a preferable constitution. SOLUTION: A substance Sr2 CuO3 having a one-dimensional copper oxide single chain (Cu-O) structure which uses a transition metal copper shows high two-photon absorption characteristics and has an extremely large effect of the third-order nonlinear polarization in the wavelength region longer than 1.5 μm. The wavelength conversion element is formed by using such a substance having a large effect of the third-order nonlinear polarization. When signal light and control light are simultaneously made to enter the wavelength conversion element and mixed, light at a new wavelength depending on the wavelengths of the two input light beams is produced and the wavelength conversion can be efficiently carried out. Not only Sr2 CuO3 but also SrCuO2 , Ca2 CuO3 or CaCuO2 are effective as the material for the wavelength conversion element.
