Single‐Step Fabrication of Smart 3D Microstructures Exploiting Naphthopyrans as Photoinitiators and Photochromic Molecules

Advanced Optical Materials, EarlyView.
Naphthopyran–benzophenone compounds can act simultaneously as photoinitiators and photochromic molecules for two‐photon polymerization. Using a single‐step process, liquid photoresist is encapsulated within polymerized 3D microstructures, preserving reversible UV–vis photochromism after fabrication.

Single‐Photon Emitters in Thickness‐Controlled hBN Directly Grown on Silicon Platform

Advanced Optical Materials, EarlyView.
Direct, catalyst‐free CVD growth produces thickness‐controlled hBN films on SiO2/Si without transfer. Growth temperature, film thickness, and carbon incorporation tune the density and single‐photon fraction of defect emitters while preserving the hBN lattice structure.

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

Advanced 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 ...
