Interface Topology Driven Loss Minimization in Integrated Photonics: THz Ultrahigh‐Q Cavities and Waveguides

Advanced Materials, EarlyView.
Compact, robust, and ultralow‐loss on‐chip photonic devices are essential for densely integrated photonic chips. Here, the underlying radiation mechanism in topological valley edge states is unveiled and a new methodology of interface topology driven bandgap and wavevector engineering is proposed to thoroughly suppress their radiation losses, thereby ...

Non-Abelian braiding of Majorana-like edge states and topological quantum computations in electric circuits [PDF]

Physical Review B, 2020
Majorana fermions subject to the non-Abelian braid group are believed to be the basic ingredients of future topological quantum computations. In this work, we propose to simulate Majorana fermions of the Kitaev model in electric circuits based on the observation that the circuit Laplacian can be made identical to the Hamiltonian.

Monolithic Terahertz Topological Mach‐Zehnder Interferometer

Advanced Materials, EarlyView.
A monolithic topological Mach‐Zehnder interferometer (MZI) is presented, integrating the splitter, combiner, and waveguide arms on a single chip. The interferometric fringes exhibiting high on‐off contrast with extinction ratios over 20 dB are achieved by utilizing tailored unit cells that facilitate interface‐dependent out‐of‐plane radiation losses ...
