Special Issue Information

Dear Colleagues,

The field of micro and nano-photonics is rapidly evolving, driven by the development of innovative materials and devices that operate at increasingly smaller scales. This special issue focuses on giving a comprehensive overview of latest advances in micro- and nano-photonics, with a particular emphasis on emerging materials, meso and nano photonics, and novel applications.

Recent breakthroughs in the synthesis and characterization of photonic materials have led to significant improvements in device performance, as well as a broadening of their applications. This issue will showcase a range of topics, including:

  • Synthesis, characterization, spectroscopy, and applications of nanoparticles
  • Synthesis, characterization, spectroscopy and applications of 2D materials
  • Spectroscopy of hybrid materials, complexes, atomic and molecular clusters, and molecular aggregates
  • Photonics of chiral micro and nanostructures
  • Photonics of anisotropic micro and nanostructures
  • Nanoand microparticles in biological research and medical diagnostics
  • Light-matter interaction in biology and medicine
  • Light-matter interaction at the mesoscale
  • Light-emitting nanostructures, nano- and microlasers
  • Photonic sensors and biosensors
  • Single-particle and single-molecule studies
  • Optical manipulation of nanoparticles and molecules, optical forces

Together, will also explore the potential of these emerging research areas to revolutionize industries such as healthcare and environmental monitoring. We invite you to contribute your cutting-edge results to this issue, highlighting the promising future of micro- and nano-photonics in fundamental research and practical applications.

This study explores the development and optical characterization of a hybrid material combining nanoporous anodic alumina with J-aggregates of pseudoisocyanine dyes, highlighting its potential for photonic applications in bright broadband sources. The hybrid material was synthesized by impregnating an alumina matrix with a dye solution, which facilitated a thermally stimulated self-assembly process for the formation of J-aggregates. The incorporation of J-aggregates within the matrix was confirmed through several independent optical measurement techniques. A distinct absorption peak and corresponding luminescence signal were attributed to J-aggregate formation, while energy transfer from the alumina’s intrinsic oxygen vacancy centers to the dye aggregates was observed under specific excitation conditions. Amplified spontaneous emission was achieved under pulsed laser excitation, characterized by spectral narrowing and a nonlinear increase in emission intensity beyond a critical pump threshold, indicative of a similarity with random lasing facilitated by scattering within the porous structure.
