Title:
ORGANIC NONLINEAR OPTICAL MATERIAL
Document Type and Number:
Japanese Patent JPH04277725
Kind Code:
A
Abstract:
PURPOSE:To improve the light transmittability in a short wavelength region and to exhibit a high quadratic nonlinear optical effect by consisting the above material of a specific compd. CONSTITUTION:An optical fiber type optical wavelength conversion element has the structure formed by coating a core 1 consisting of an org. nonlinear optical material with a clad 2 consisting of a material, such as glass, which does not exhibit the nonlinear optical effect. The compd. expressed by formula exhibits the high quadratic nonlinear optical effect by using a technique of determining the molecular structure adequate for the nonlinear optical element. This compd. is usable adequately particularly as the org. nonlinear optical material for a second harmonic generating element. In the formula I, R<1>, R<2> denote a hydrogen atom or alkyl group which may have a substituent; R<3> denotes an alkyl group or alkoxy group which may have a substituent; R<4> denotes an amino group or alkyl group which may have a substituent.
