Topological photonics for optoelectronic sensing — •Jakob Lindenthal1,2, Johannes Benduhn1, and Karl Leo1,21Institute of Applied Physics, Technische Universität Dresden — 2ct.qmat - Würzburg-Dresden Cluster of Excellence

Topological properties of photonic systems are a quickly emerging research field. The physical realisation of topological invariants allows the creation of photonic states with strong protection of the state's existence against perturbation. The energy levels of topological states can be made highly sensitive to external influences, enabling the design of novel optoelectronic sensing devices. Theoretical concepts of different topological photonic systems are discussed, and experimental systems are showcased. The presentation reports about an optoelectronic pressure sensor developed at the Institute of Applied Physics at TU Dresden and other devices fabricated by partnering organisations. Key concepts and technological advantages of topological systems are summarised, highlighting the prospects for incorporating topology in optoelectronic sensing devices.
