HIGHLIGHTS
- who: Hongwei Wang from the (UNIVERSITY) have published the article: Ultracompact topological photonic switch based on valley-vortex-enhanced high-efficiency phase shift, in the Journal: (JOURNAL)
- what: In experiments the authors show a 1.57-fold improvement in u03c0-phase tuning efficiency. By leveraging the high-efficiency phase-shifting properties and the sharp-turn features of the waveguide the authors demonstrate an 1 u00d7 2 thermo-optic (TOTS) operating at telecommunication wavelengths. Topological switch Based on the topological phase shifter, the authors propose an ultracompact 1 u00d7 2 TOTS, as shown in Fig 3a . . .
