    We developed a planar integrated optics configuration for 3D multistage interconnection networks. Experimental results show feasibility for cascading operations, achieving ~42% of the theoretical beam combination efficiency limit.

    Area of Science:

    • Optics and Photonics
    • Computer Science
    • Electrical Engineering

    Background:

    • Multistage interconnection networks (MINs) are crucial for parallel computing.
    • Planar integrated optics offer a scalable platform for optical interconnects.
    • Cascading operations in optical networks require efficient signal and power beam management.

    Purpose of the Study:

    • To propose and validate a planar integrated optics configuration for 3D MINs.
    • To demonstrate the feasibility of cascading operations within this optical architecture.
    • To experimentally measure the efficiency of beam combination at a network node.

    Main Methods:

    • Configuration design for planar integrated optics in 3D MINs.
    • Experimental setup for beam combination of signal and power arrays.
