Abstract
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.

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.
