Optical Studies of Self-Assembled Meta-Gratings

That’s great(ing)!

This thesis explores the study and application of optical gratings, which play a central role in many optical systems. Optical gratings are used in fields such as spectroscopy, telecommunications, laser optics, and sensor technology due to their ability to split light into its spectral components. Their versatility makes them essential building blocks of modern scientific and technological applications.\

A particular focus is on the development and production of new types of optical gratings using innovative laser manufacturing processes. In particular, the process of laser-induced deposition (LID) is being investigated, which enables the targeted synthesis of metal structures on a wide variety of surfaces. By using a laser and metallic nanoparticles, functional optical gratings can be produced.\

In this work, the prefabricated optical gratings produced by Manshina group (St. Petersburg State University) using the LID (laser-induced deposition) method are analyzed in detail. The focus is on the structural and functional properties of these gratings. Optical analyses are carried out to evaluate the efficiency of the gratings in the diffraction and transmission of light.\

The results provide insights into the performance of optical gratings produced using the LID (Laser-induced deposition) process. It is shown that these gratings not only have a high optical quality, but can also be used effectively in various applications.
