Special Issue Information

Dear Colleagues,

Glass-based optical devices have experienced continual developments, both in the advancement of fiber amplification and laser sources and photonic components in general.

Fiber lasers have significantly increased output power and spectral width, also thanks to novel microstructuring schemes, while, similarly, improved fabrication technologies have allowed the fabrication of advanced geometries.

As a prerequisite, improved materials and novel composites, in particular involving harnessing the formation or inclusion of nanoparticles in glasses, have been developed and have allowed these advancements.

This Special Issue on “Fiber Lasers and Glass Photonics: Materials through Application” aims to focus on this combined and correlated evolution of materials toward devices.

Subjects of the research articles to be published in this Special Issue therefore include but are not limited to:

  • Novel glass materials for fiber and photonic devices (e.g., glass ceramics, rare-earth doped glasses);
  • Advanced structure geometries for fiber lasers and glass photonic devices;
  • Plasmonic effects in glass materials;
  • Fabrication technologies and processes;
  • Nonlinear devices;
  • Flexible photonic devices;
  • Fiber and planar waveguide lasers based on glasses emitting at visible, near and medium infrared wavelengths;
  • Optical microresonators.

We expect that articles published in this Special Issue will offer a comprehensive picture of the most recent trends in glass development and the evolution of devices based on this material class.

Abstract
Microresonator-based lasers in the two-micron range are interesting for extensive applications. Tm3+ ions provide high gain; therefore, they are promising for laser generation in the two-micron range in various matrices.

Microresonator-based lasers in the two-micron range are interesting for extensive applications. Tm3+ ions provide high gain; therefore, they are promising for laser generation in the two-micron range in various matrices. We developed a simple theoretical model to describe Tm-doped glass microlasers generating in the 1.9–2 μm range with in-band pump at 1.55 μm. Using this model, we calculated threshold pump powers, laser generation wavelengths and slope efficiencies for different parameters of Tm-doped tellurite glass microspheres such as diameters, Q-factors, and thulium ion concentration. In addition, we produced a 320-μm tellurite glass microsphere doped with thulium ions with a concentration of 5·1019 cm−3. We attained lasing at 1.9 μm experimentally in the produced sample with a Q-factor of 106 pumped by a C-band narrow line laser. Full article
