High‐Performance Near‐Infrared Organic Light‐Emitting Diodes Based on Grating‐Structured Hole Transport Layer

open access: yesSmall Structures, Volume 7, Issue 8, August 2026.
High‐performance near‐infrared (NIR) organic light‐emitting diodes (OLEDs) were achieved by incorporating a one‐dimensional Bragg grating into a thermally cross‐linkable hole‐transporting layer via microtransfer molding. The optimized devices exhibit an emission peak at 880 nm, a maximum external quantum efficiency of 1.55%, and a peak radiant exitance

Optical vortex fiber laser based on modulation of transverse modes in two mode fiber

open access: yesAPL Photonics, 2019
Optical vortices, characterized by helical phase fronts, are usually generated outside the laser cavity using passive modulation methods. Here, we demonstrate an all-fiber laser to directly deliver mode-locked and continuous-wave vortex beams based on ...
