About this Research Topic
As a powerful 3D processing technique, femtosecond laser micromachining has been applied to produce different types of optical and photonics structures in transparent materials in a flexible and cost-effective way. Applications based on the achieved waveguides have been fulfilled including waveguide lasers, nonlinear harmonics generation, laser beam shaping, sensors and microfluidics in transparent materials, such as crystals, ceramics, glasses and polymers. The current demand for photonic devices with excellent performances prompts the further advancement of fs-laser micromachining as a promising methodology enabling surface and bulk modifications in the transparent materials.
Herein, the main goal of this Research Topic is to bring together novel and interesting waveguide structures fabricated by fs-laser micromachining working at different wavelengths in transparent materials, and their applications.
Within the scope of this Research Topic, authors are encouraged to submit their recent findings of passive and active fs-laser inscribed guiding structures. Studies on laser beam shaping, waveguide lasers, and optical modulation are invited. In particular, we warmly welcome articles covering the following themes:
- Physics of modification of transparent materials through fs-laser micromachining
- fs-laser fabricated novel and flexible guiding structures for integrated components
- Fabrication of 2D and 3D waveguides in silica
- Innovative approaches of optical microfluidics fabricated by fs-laser micromachining
- Newly established studies of waveguide lasers fabricated by fs-laser inscription
- Optical nonlinear performances of waveguides achieved in distinct materials
- fs-laser inscribed gratings in waveguides
