Deep Neural Network This cover illustrates a novel deep learning approach for designing high-performance blue light grating couplers in visible light photonic integrated circuits. The artwork depicts an artificial neural network optimizing a silicon nitride grating to efficiently couple a vertical blue laser into a waveguide. This AI-driven method achieves 95% accuracy, accelerating next-generation short-wavelength photonic device development. More details can be found in the Research Article by Chao Shen and co-workers (DOI: 10.1002/adom.202501822).
