Exploring the Role of Artificial Intelligence in Precision Photonics: A Case Study on Deep Neural Network‐Based fs Laser Pulsed Parameter Estimation for MoOx Formation

open access: yesAdvanced Photonics Research, EarlyView.
Ultrafast pulsed laser technology enables precise material processing. This study examines molybdenum oxide formation under varying laser parameters. A dataset of 187 samples is generated, and eight deep neural networks (DNNs) with different architectures are trained. Models are validated using three learning rates and evaluated with mean squared error,

Diffractive Synthesis of Multipole Interference States Using Low‐Index Mesoscale Dielectric Structures

open access: yesAdvanced Photonics Research, EarlyView.
Multipole interference (MPI) plays pivotal roles in electromagnetics. In optics, it has been realized typically with the Mie resonance in high‐index, deep‐subwavelength‐scale dielectric resonators. A new, diffraction‐based MPI scheme is proposed and demonstrated with low‐index, mesoscale dielectric structures.

Low‐Loss Parowax‐Imprinted Diffractive Neural Network for Orbital Angular Momentum Terahertz Holographic Imaging

open access: yesAdvanced Photonics Research, EarlyView.
This work introduces a low‐loss diffractive neural network, fabricated using an imprinting technique with parowax material, for recognizing and manipulating the topological charge of orbital angular momentum (OAM) waves. It is also demonstrated that the low‐loss diffractive network can perform mathematical operations based on the topological charges of
