Indium gallium arsenide phosphide spontaneously emits light when excited by a laser, with this light populating the edge state that exists between the topologically distinct materials. This edge state can then be used to make a scattering-proof laser cavity of any shape.

Topological insulator laser experiments

Recent experiments, which in great agreement with theoretical predic-tions, con rm that. In this review, we rst brie y review topological insulators’ theory and get some intuition what topology state means, and then construct basic 2015-09-03 On the technological side, the topological insulator laser provides a route to make many semiconductor lasers to operate as a single-mode high-power laser, while coupled efficiently into an output (Nanowerk News) Israeli and US researchers have developed a new, highly efficient coherent and robust semiconductor laser system: the topological insulator laser. The findings are presented in two new joint research papers, one describing theory ( "Topological insulator laser: Theory" ) and the other experiments ( "Topological insulator laser: Experiments" ), published online today by the prestigious journal Science . Applying topological physics to lasing creates more highly efficient and robust lasers.
