Optimization of GaN Bent Waveguides in the Visible Spectrum for Reduced Insertion Loss

Optimization of GaN Bent Waveguides in the Visible Spectrum for Reduced Insertion Loss

The development of GaN-based photonic integrated chips has attracted significant attention for visible light communication systems due to their direct bandgap and excellent optical properties across the visible spectrum. However, achieving compact and efficient light routing through bent waveguides...
