광학소자 제조를 위한 비선형광학 Polycarbonate의 합성 연구
Synthesis of Nonlinear Optical Polycarbonate for Optical Device Applications
초록
비선형광학 고분자를 이용하여 광학소자를 제조할 때 나타나는 문제점들인 열적 안정성, 박막 형성시의 crack 형성, 광 손실 등의 문제점들을 해결하기 위하여 고분자의 주사슬을 축중합에 의한 polycarbonate로 바꾸고 발색단으로 disperse red 1을 부착시킨 비선형광학 고분자를 합성하였다. 합성된 비선형광학 polycarbonate는 매우 우수한 열 안정성을 보였고 일반적인 용매를 사용하여 spin costing 방법으로 박막을 제조할 수 있었다. 비선형광학 polycarbonate를 50V/㎛로 poling 하였을 때 633nm와 1.3㎛에서 각각 14pm/V와 4pm/V의 전기광확계수 값을 얻었다.
In order to solve the problems, such as thermal stability, crack formation in thin films, and optical loss, occurring when optical devices are made of nonlinear optical (NLO) polymers, a new NLO polymer of polycarbonate with disperse red 1 as a chromophore was systhesized. The new NLO polymer exhibits excellent thermal stability and good solubility for common solvents for spin coating. The new NLO polymer has values of electro-optic coefficient of 14 pm/V and 4 pm/V at 633 nm and 1.3 μm, respectively, when the polymer was poled at 50 V/μm.
