Накратко на български

Течните кристали с хирални структури, подобни на лявата и дясната ръка, се изследват за управление на светлината в микромащаб. Това помага за разработването на по-енергоефективни фотонни устройства, които да намалят разхода на енергия при предаването на данни.

Interacting optical and topological solitons in frustrated cholesterics

Fiber optic data transmission exploiting the photon as the information carrier rather than the electron has revolutionized the way we do business and our ability to process ever-increasing amounts of data in record time. Being an integral part of consumer high-speed internet, it is one of the most well-known achievements of the field of photonics—the study of the generation, transmission, manipulation and detection of light. However, current technologies based on costly and power-hungry photon→electron→photon conversion appear insufficient in light of environmental constraints. Going beyond state-of-the-art solid materials for photonics applications, the EU-funded OPTOSOL project was investigating novel light-matter interactions in so-called “topological soft materials”—complex liquid-crystalline fluids which embed robust birefringent structures allowing the manipulation of the flow of light at the microscopic scale. The objective of the OPTOSOL project was to determine the guiding principles of light in chiral soft materials which cannot be superimposed on their mirror images—like the left and right hands. These malleable materials can be reconfigured in real-time with external fields and allow the exploration of alternative routes for the management of light for which solid-state materials are not best suited, potentially unlocking new physical phenomena aiding the design of energy-efficient photonics devices.

Цел на проекта

In our ever-growing digital world, finding fast and efficient ways of manipulating and transmitting information unlocks the possibility to implement more efficient business models (using big data, cloud computing, deep learning...). Amidst a number of concurrent fields (electronics, spintronics, amtronics...), photonics aims to address this technological need by exploring novel means for the generation, transmission, manipulation and detection of light. In this proposal, we want to develop a new research direction by combining knowledge from photonics and topological soft matter to find novel ways of guiding light using chiral birefringent media. The non-linear optical response of these media allows a laser beam to be self-confined and to propagate over long distances, leading to what is called spatial optical solitons. Our primary objective is to develop a complete model of optical solitons in chiral birefringent media and examine how these light solitons can be steered and controlled using topological solitons — localized and tunable perturbations of the molecular orientational field which cannot be continuously deformed into the uniform state. Our methodology will be based on the theoretical and numerical modeling of the non-linear equations for the propagation of light in chiral birefringent media, combined with collaborative experiments. This fellowship is designed to include an excellent training both on scientific skills (mainly photonics and topology, for which the expertise of the host group will be essential) and transferable skills such as leadership, project and data management, intellectual property rights, etc. The training that I will receive on photonics — a major field both in the academic and industry sector — will also provide a significant boost on my career prospects.
