초록

16.6${\mu}m$ 주기로 리튬나오베이트 Ti 확산 채널광도파로를 분극반전 시킨 Ti:PPLN을 이용해서 편광모드변환을 기반으로 하는 $\check{S}$olc-형 파장필터를 구현하여, 실험적으로 투과 광 스펙트럼을 측정하였다. 중심파장 1272.49nm에서 투과 스펙트럼이 관찰되었으며, 투과 스펙트럼의 선폭(FWHM)과 부모드 레벨이 각각 0.23nm and 7dB로 측정되었다.

We demonstrated $\check{S}$olc-type wavelength filters in periodically poled Ti-diffused lithium-niobate channel optical waveguide (Ti:PPLN). A $\check{S}$olc-type transmission spectrum based on the polarization-mode conversion was observed experimentally in PPLN with period 16.6${\mu}m$. A reasonable explanation of such a phenomenon was presented. A polarization-mode converted transmission peak was observed at wavelength 1272.49nm. The FWHM and sidelobe of spectrum are about 0.23nm and 7 dB, respectively.
