Effect of Core Geometry on Frequency Correlations and Channel Capacity of a Multimode Optical Fiber

Advanced Photonics Research, EarlyView.
Structured wavefronts focused at the output of multimode fibers reveal a distinct spatial dependence of frequency correlation bandwidth between circular and rectangular cores. Unlike conventional circular‐core fibers, rectangular‐core fibers maintain uniform bandwidth across all transverse locations, enabling over a 20% increase in channel capacity for

Analysis of Band Effects in One‐Dimensional Periodic Lattices Using an Enhanced Homogenization Method

Advanced Photonics Research, EarlyView.
An enhanced homogenization method for periodic lattices, applicable to any asymmetrical multipart structures, is proposed. This method simplifies intricate gratings into slab waveguides, predicts guided‐mode resonances and bound states in the continuum, without relying on numerical methods.

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

Advanced 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.

Extraction of Inherent Amplitude Mode from a Light Beam

Advanced Photonics Research, EarlyView.
Mode extraction is the inverse process of the double‐beam superposition principle in classical optics. While polarization mode extraction has been successfully demonstrated using an m‐order vector vortex beam, this article demonstrates the amplitude mode extraction of a light beam.

Digitized Phase‐Change Material Heterostack for Transmissive Diffractive Optical Neural Network

Advanced Photonics Research, EarlyView.
A phase‐change‐material‐based digitized heterostack is experimentally demonstrated and theoretically analyzed for future energy‐efficient, fast reconfigured, and compact transmissive diffractive optical neural networks. All‐optical and fully reconfigurable transmissive diffractive optical neural network (DONN) architectures emerge as high‐throughput ...
