ˆ¥ŽA•¶Optical materials with novel properties arising due to their structuring on micro- and nano-scale are currently highly sought in optics and photonics. Although advances in modern nanotechnology have made many structuring techniques available for research and industry, there is a growing need for cost- and throughput-efficient fabrication techniques. Laser lithography is applicable to a wide range of materials, with spatial resolution on the order of 100 nm. This method, based on exposure of photosensitive media (such as photoresists) with spatially shaped laser beams, is natively suited for 3D structuring, and is economical, as it does not require high-vacuum or ultra-clean environment. This study is aimed at perfecting laser lithography for the fabrication of optical materials. We will focus on fast prototyping of high-resolution photoresist masks suitable for subsequent post-processing (e.g., by etching, thin film deposition, and metallization), and on preparation of metallo-dielectric frequency-selective surface structures suitable for optical detection and sensing applications. Using the same approach, reversible optical structuring of photonic structures in photorefractive lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) crystals will be studied as a route towards structures allowing dynamical all-optical control over optical energy propagation and information storage (optical waveguides, photonic lattices, optical memory bits).
