본 연구에서는 슬롯 도파관을 기반으로 한 소형 광편파 변환기(PC)를 제안했습니다. Si 도파관과 SiO 사이의 높은 굴절률 대비 활용2 Silicon-on-Insulator 플랫폼에 클래딩을 적용하면 광선이 슬롯 도파관 구조에 강력하게 제한될 수 있습니다. 제안된 PC는 정사각형 도파관과 L- 모양 커버 도파관. 전체 구조가 수평 방향에서 45도 회전된 축을 따라 대칭으로 분포되어 있기 때문에 이 PC의 광축은 입력 및 출력 끝의 두 직교 편광 모드에서 등각 방향에 놓이게 되어 높은 광도를 제공합니다. 편광 변환 효율(PCE). 3D FDTD 시뮬레이션 결과는 TE-to-TM 모드 변환이 8.2μm의 장치 길이로 달성되고 PCE가 99.8%를 초과한다는 것을 보여줍니다. PC의 구조적 허용 오차와 파장 의존성도 자세히 논의되었습니다.

Abstract: A compact optical polarization converter (PC) based on slot waveguide has been proposed in this study. Utilizing the high refractive index contrast between a Si waveguide and SiO2 cladding on the silicon-on-insulator platform, the light beam can be strongly confined in a slot waveguide structure. The proposed PC consists of a square waveguide and an L-shape cover waveguide. Since the overall structure is symmetrically distributed along the axis rotated 45-degree from the horizontal direction, the optical axis of this PC lies in the direction with equi-angle from two orthogonally polarized modes of the input and output ends, which leads to a high polarization conversion efficiency (PCE). 3D FDTD simulation results illustrate that a TE-to-TM mode conversion is achieved with a device length of 8.2 µm, and the PCE exceeds 99.8%. The structural tolerance and wavelength dependence of the PC have also been discussed in detail.
