Applying topological physics to lasing creates more highly efficient and robust lasers. Haifa, Israel February 1, 2018 –Israeli and US researchers have developed a new highly efficient coherent and robust semiconductor laser system: the topological insulator laser. h2020,topo ins laser,erc-2017-adg,technion - israel institute of technology(il) Segui le ultime notizie e i progetti sulla Covid-19 e la risposta della Commissione europea al coronavirus. Skip to main content We report on the first demonstration of electrically pumped topological insulator laser arrays. When pumping is applied to the elements along the perimeter, 10 Jan 2020 Here we report an all-dielectric topological insulator laser scheme based on semiconductor cavities formed by topologically distinct Kagome Topological insulator laser was first experimentally reported in magneto-optical photonic crystals pumped by a static magnetic field to break time-reversal 5 Feb 2018 Stewart Wills. Ring resonator array with lasing on edge.
Our result indicates that like the atomic layer graphene, the topological insulator Bi2Se3 could also operate as an effective saturable absorber for the passive mode locking of lasers at the telecommunication band.

We introduce a class of topological lasers based on the photonic Floquet topological insulator concept. The proposed system is realized as a truncated array of lasing helical waveguides, where the We introduce a class of topological lasers based on the photonic Floquet topological insulator concept. 2020-10-07 · (a) Topological insulator: a two-dimensional (2D) material that is insulating in the bulk but exhibits perfect conduction on the edge.
