초록

단일모드 광섬유와 평면도파로 결합기의 파장선택성을 이용한 고감도 온도센서를 구현하였다. 폴리머 평면도파로의 높은 열광학 효과에 의하여 결합기의 공진파장이 -3.43㎚/℃ 정도로 매우 민감하게 이동함을 관찰할 수 있었다. 소자의 편광의존성을 줄이고 온도에 대한 감도를 증가시키기 위한 설계 기법을 제시하였다.

High-senstivity temperature sensor based on the wavelength selectivity of single mode fiber-to-planar waveguide coupler, was demonstrated. The resonant wavelength of the coupler was shifted with large rate of -3.43nm/$^{\circ}C$ owing to good thermo-optic effects of polymer planar waveguide. The device design technique to reduce the polarization dependent properties and increase the temperature sensitivity was presented.
