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

open access: yesAdvanced 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

Spherical and Aspherical Lenses for Boosting the Performance of Terahertz Imaging Systems

open access: yesAdvanced Photonics Research, EarlyView.
This study investigates the enhancement of terahertz (THz) detection through the terajet effect using mesoscale dielectric lenses of various geometries. Spherical, aspherical, and cubic polytetrafluoroethylene lenses are evaluated at 0.15 and 0.3 THz, demonstrating significant improvements in responsivity and noise reduction.
