(3+1)D Printing of Core–Clad Waveguide by Two‐Photon Polymerization
Low‐loss, single‐mode core–clad optical waveguides are fabricated using a novel (3+1)D multiphoton polymerization technique in a hybrid resin. Precise laser power control and multi‐pass exposure enable refractive index engineering and reduce scattering. Raman spectroscopy confirms the correlation between polymerization and index change.

Hybrid Electroluminescence Device for On‐Demand Single Photon Generation at Room Temperature
New type of electroluminescent device based on hBN nanocrystals deposited on a GaN laser diode displays electrically driven emission of single photons at room temperature. Low g2(0) autocorrelation function values are achieved of < 0.2 for continuous driving and < 0.4 for on‐demand single‐photon emission.

3D Printed Optics Achieves Broadband Structured Light
The arbitrary creation of structured light often requires complex design and fabrication steps and is largely limited to single wavelength. By leveraging off the toolkit for digital holograms, how complex amplitude modulation can be implemented as 3D printed optics in a manner that is broadband is shown, for the creation of multiwavelength forms ...
