Abstract

본 발명은 LB법을 이용한 유기물 geodesic도파토 렌즈의 제작방법에 관한 것이다. 종래의 spin coating에 의한 유기물 도파로 제작방법으로는 spin coating후에 렌즈가 되기 위해 필요한 평면 광도파로의 곡면형태가 유지되지 않기 때문에 goedesic렌즈의 제작이 불가능하다.The present invention relates to a method for manufacturing an organic geodesic dopato lens using the LB method. In the conventional method of fabricating organic waveguides by spin coating, it is impossible to manufacture goedesic lenses because the curved shape of the planar optical waveguide required to become a lens after spin coating is not maintained.

그러나 10A정도의 유기물층을 한층 한층 geodesic도파로 렌즈를 의한 곡면이 형성된 기판위에 이전시키는 LB법을 이용하면 렌즈의 곡면을 그대로 유지시키면서 도파로층의 형성이 가능하기때문에 유기를 geodesic 도파로 렌즈의 제작이 가능하다.However, the LB method of transferring the organic layer of about 10A onto the substrate having the curved surface by the geodesic waveguide lens enables formation of the waveguide layer while maintaining the curved surface of the lens as it is. .

따라서 유기물의 다양한 선형 및 비선형 특성을 이용한 2차원 신호처리소자 제작을 위한 기본부품으로서 사용이 가능하고, 또한 광 집적회로에 사용이 가능하게 된다.Therefore, it can be used as a basic component for manufacturing two-dimensional signal processing elements using various linear and nonlinear characteristics of organic materials, and also can be used in optical integrated circuits.
