This research demonstrates a 3D multi-tip edge coupler achieving 73% efficiency at 775 nm, highlighting advanced grayscale lithography for improved coupling.
We present a 3D multi-tip edge coupler for 775 nm, achieving a low loss of 1.37 dB (73% efficiency), leveraging grayscale lithography to simplify fabrication while maintaining high-performance mode-conversion and fiber-to-chip coupling.
