Guidelines

Novel photonic structures with various functionalities acquired enormous attention recently as promising solutions for novel information technologies, including artificial intelligence. Time reversal symmetry breaking in such structures can result in highly unidirectional propagation of light. Moreover, the spin angular momentum as a degree of freedom of light at the nanoscale offers the ability to influence and exploit light-matter interactions which can allow precise control of light propagation even without time reversal symmetry breaking via spin-momentum locking in the so-called topological photonic systems or in some 2D materials. This opens the way to a control of light propagation of large interest for integrated nanophotonic circuits.
The study will be focused to design and simulate optical response of photonic structures which utilize the time reversal symmetry as well as its breaking in order to precisely control the propagation of light. This can be done statically via proper design of photonic band structure or dynamically via the change of the lateral geometry, magnetization or polarization. The student will utilize and further develop advanced simulation approaches, such as FDTD, FDFD, RCWA, etc. and the results will be confirmed experimentally via collaboration with other laboratories. The material system choice will be focused to optically friendly magnetic materials (such as ferrimagnetic garnets, novel 2D materials), magnetic ferroelastic materials (such as Ni-Mn-Ga) or ferroelectric materials. Finally, biosensing properties of designed photonic structures will be exploited as well.
