研究目的
To propose a novel coupling device composed of a microlens and a pillar on the end face of SMF for high efficiency optical coupling in silicon photonics applications.
研究成果
The proposed coupling device with microlens and pillar on SMF end face offers high coupling efficiency, broad coupling bandwidth, and low polarization dependence, suitable for SiPh interconnect applications.
研究不足
Alignment between the aperture of the mask and the core of SMF end face is not practical, requiring active alignment due to very small 'hot spot'.
1：Experimental Design and Method Selection:
The study proposes a novel coupling device fabricated using self-written waveguide (SWW) method with UV-curable resin.
2：Sample Selection and Data Sources:
Single mode fiber (SMF) and silicon photonics (SiPh) devices are used.
3：List of Experimental Equipment and Materials:
UV-curable resin 'SUNCONNECT' by Nissan Chemical Corporation, 406 nm wavelength laser.
4：Experimental Procedures and Operational Workflow:
Fabrication involves forming optical pillars on SMF using SWW method and creating microlens by dipping method.
5：Data Analysis Methods:
Numerical analysis for spot size and beam waist position as a function of microlens radius of curvature.
