Design of Prismatic Beams for Bending

427
The design of prismatic beams, structural elements with a uniform cross-section, focuses on ensuring safety and structural integrity under load. The design process begins by determining the allowable stress, either from material properties tables, or by dividing the material's ultimate strength by a safety factor. This safety factor is essential for accommodating uncertainties, and varies depending on the material—timber, steel, or concrete—with each having unique strength and...

    Area of Science:

    • Optoelectronics
    • Optical Engineering
    • Fiber Optics

    Background:

    • Fiber optical power splitters (OPSs) are crucial components in optical communications, sensing, and lasers.
    • Variable power ratio OPSs enhance optical system flexibility and structural simplicity.
    • Existing OPS designs may lack continuous tunability or optimal configuration.

    Purpose of the Study:

    • To propose and demonstrate a novel variable fiber OPS.
    • To investigate a triangular prism-based design for continuous power ratio tuning.
    • To compare horizontal displacement with traditional tilt angle designs for OPS.

    Main Methods:

    • A variable fiber OPS was designed using a dual-fiber collimator, focus lens, and a 120° triangular prism.
    • Optical simulations were performed to evaluate design performance.
    • The axial displacement of the prism was manipulated to adjust the power splitting ratio.
    • Polarization and wavelength dependence were analyzed.

    Main Results:

    • The proposed triangular prism-based OPS allows continuous tuning of the power splitting ratio from 50:50 to 90:10.
    • Optical simulations indicated that a horizontal displacement design is superior to a traditional tilt angle design.
    • The device's performance was evaluated concerning polarization and wavelength dependence.

    Conclusions:

    • A functional variable fiber OPS based on a triangular prism was successfully demonstrated.
    • The horizontal displacement method offers improved performance for variable power splitting.
    • This technology provides a flexible and adaptable solution for optical systems requiring adjustable power division.
