Carbon‐Coated Moth‐Eye Structure: An Ultrabroadband THz‐DUV Near‐Perfect Absorber

open access: yesAdvanced Optical Materials, EarlyView.
A silicon moth‐eye surface coated with pyrolytic carbon achieves >98% absorption from 1 to 1200 THz by combining gradient‐index matching with PyC's broadband conductivity, forming an ultra‐broadband absorber from THz to deep UV. Experimental results and simulations agreed well.

Evolution of Collective, Radiative Plasmon Coupling in Confined, Soft Colloidal Films

open access: yesAdvanced Optical Materials, EarlyView.
Plasmon resonance coupling is continuously monitored during the uniaxial manipulation of a 2‐dimensional soft colloidal film containing hexagonally arranged spherical gold nanocrystals. This is realized by the in situ spectroscopic investigation of a monolayer of plasmonic core‐shell microgels confined at the air/water interface that is compressed in a

Harnessing Ultrafast Optical Pulses for 3D Microfabrication by Selective Tweezing and Immobilization of Colloidal Particles in an Integrated System

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...

Proving Optical Anisotropy and Polarization Effects in β‐Ga2O3$\left(\text{Ga}\right)_{2} \left(\text{O}\right)_{3}$ Nanomembranes via X‐Ray Excited Optical Luminescence

open access: yesAdvanced Photonics Research, EarlyView.
In this study, the pronounced anisotropy in the optical properties of β‐Ga2O3 nanomembranes has been analized under a synchrotron nanoprobe. We have investigated the site‐specific contributions of distint Ga ions to the emission bands by combining polarization‐dependent X‐ray absorption near‐edge structure and X‐ray excited luminescence.

Effect of Nanoparticle Distribution on Photothermal Absorption in Binary Mixtures of Colloidal Supraballs

open access: yesAdvanced Photonics Research, EarlyView.
This work combines molecular dynamics and finite‐difference time‐domain computational approaches to study the photothermal properties of melanin nanoparticle–based supra‐assemblies. Based on the results of this study, the binary mixtures of melanin and silica with higher concentrations of melanin and with more segregated levels of mixing are able to ...

Incoherent Digital Holography Empowered by Wavefront and Information Engineering: A Review

open access: yesAdvanced Photonics Research, EarlyView.
Advancements in incoherent digital holography (IDH) have been achieved via wavefront engineering (using spatial light modulators, diffractive optics, and metasurfaces) and information engineering (using compressive sensing and deep learning). This paper presents an overview of IDH with wavefront and information engineering, paving the way toward its ...
