Researchers from the Holography and Optical Processing Group (GHPO) have achieved a breakthrough in the field of high-precision laser printing by successfully printing tunable materials for the first time. This groundbreaking development, published in the prestigious journal Optics Express, showcases the ability to print polymers doped with liquid crystals, thereby opening new possibilities for the environmentally friendly production of tunable devices using this fast and precise technique.
Professor Daniel Puerto, the head of the research team, explains that this technological advancement enables the manufacturing of lenses with materials that change their properties when subjected to electrical voltage. This innovation holds immense potential for the use of such devices in the fields of microscopes, optical microdevices, and other technological applications.
The research was a collaborative effort led by the UA group, comprised of researchers Sergi Gallego, Manuel Ortuño, Andrés Márquez, Jorge Francés, Inmaculada Pascual, and Augusto Beléndez. Additionally, researchers Catalin Constantinescu and Patricia Alloncle from the LP3 laboratory of the Center National de la Recherche Scientifique (CNRS, France), as well as researcher Camilo Florian from Princeton University (U.S.), contributed to the study.
Optical devices utilizing tunable materials play a crucial role in communication technologies, enabling functions like optical switching and multiplexing. Traditionally, the manufacturing process for these devices has been time-consuming and costly. However, the utilization of ultra-short pulse lasers (with durations ranging from 10-12 to 10-15 seconds) has revolutionized laser processing techniques, allowing for faster and more sustainable production.
The expertise of the Holography and Optical Processing Group, led by lecturers Augusto Beléndez and Inmaculada Pascual, has paved the way for a new research avenue in the manufacturing of tunable devices, including lenses and waveguides, using laser printing techniques.
According to Daniel Puerto, the usage of polymer-based materials is advantageous in the development of foldable technologies like mobile phones and tablets. In this regard, the flexibility of polymers is crucial. Notably, until now, it had not been possible to print polymers with liquid crystals. Thus, the successful achievement of this technique opens up a wide range of possibilities in the field of tunable devices.
