Dynamic Phase Enabled Topological Mode Steering in Composite Su-Schrieffer-Heeger Waveguide Arrays
Min Tang, Chi Pang, Christian N. Saggau +10
Topological boundary states localize at interfaces whenever the interface implies a change of the associated topological invariant encoded in the geometric phase. The generically p…
Symmetry induced selective excitation of topological states in SSH waveguide arrays
Min Tang, Jiawei Wang, Sreeramulu Valligatla +10
The investigation of topological state transition in carefully designed photonic lattices is of high interest for fundamental research, as well as for applied studies such as manip…
Experimental Observation of Berry Phases in Optical Moebius-strip Microcavities
Jiawei Wang, Sreeramulu Valligatla, Yin Yin +9
The Moebius strip, as a fascinating loop structure with one-sided topology, provides a rich playground for manipulating the non-trivial topological behavior of spinning particles,…
Topological phase transition in a stretchable photonic crystal
Ehsan Saei Ghareh Naz, Ion Cosma Fulga, Libo Ma +2
We design a setup to realize tunable topological phases in elastic photonic crystals. Using the Su-Schrieffer-Heeger (SSH) model as a canonical example, we show how a system can be…
Topology induced anomalous plasmon modes in metallic Mobius nanorings
Yin Yin, Shilong Li, Vivienne Engemaier +4
We report on the investigation of plasmonic resonances in metallic Möbius nanorings. Half-integer numbers of resonant modes are observed due to the presence of an extra phase π pro…
Hybridization of photon-plasmon modes in metal-coated microtubular cavities
Yin Yin, Shilong Li, Vivienne Engemaier +4
The coupling of resonant light and surface plasmons in metal layer coated optical microcavities results in the formation of hybrid photon-plasmon modes. Here, we comprehensively in…
Localized surface plasmons selectively coupled to resonant light in tubular microcavities
Yin Yin, Shilong Li, Stefan Böttner +5
Vertical gold-nanogaps are created on microtubular cavities to explore the coupling between resonant light supported by the microcavities and surface plasmons localized at the nano…
Vertical optical ring resonators fully integrated with nanophotonic waveguides on silicon-on-insulator substrates
Abbas Madani, Moritz Kleinert, David Stolarek +3
We demonstrate full integration of vertical optical ring resonators with silicon nanophotonic waveguides on silicon-on-insulator substrates to accomplish a significant step towards…
Non-integer optical modes in a Möbius-ring resonator
S. L. Li, L. B. Ma, V. M. Fomin +3
In-plane polarized light experiences a non-trivial topological evolution as it propagates resonantly in a Möbius ring resonator. The resultant geometric phase varies continuously w…
