    We developed compact, high-efficiency 45-degree waveguide bends using perfluorcyclobutyl (PFCB) copolymers. These bends demonstrate low insertion loss for optical communication applications.

    Area of Science:

    • Materials Science
    • Optical Engineering
    • Photonics

    Background:

    • Low refractive index contrast waveguides are crucial for compact photonic integrated circuits.
    • Efficient waveguide bends are essential for routing light within these circuits.
    • Perfluorcyclobutyl (PFCB) copolymers offer desirable properties like high glass transition temperature and low optical loss.

    Purpose of the Study:

    • To design, fabricate, and measure the performance of 45-degree single air interface bends.
    • To achieve high efficiency and compactness in low refractive index contrast waveguides.
    • To utilize PFCB copolymers in a low refractive index material system for these bends.

    Main Methods:

    • Standard microfabrication techniques were employed for waveguide fabrication.
