Topological insulator laser experiments

Zak, J. Berrys phase for energy bands in solids. Phys. Rev. Here we demonstrate a nonmagnetic topological insulator laser system exhibiting topologically protected transport in the cavity. Its topological properties give rise to single-mode lasing, robustness against defects, and considerably higher slope efficiencies compared to the topologically trivial counterparts. 2020-10-07 · The first topological insulator laser was actually demonstrated in experiments a few months earlier and it displayed all the expected features (see Figure 5) .

The topological properties give rise to single mode lasing, robustness against defects, and significantly higher slope efficiencies compared to the topologically trivial counterparts. Here we demonstrate a nonmagnetic topological insulator laser system exhibiting topologically protected transport in the cavity.

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 Ghimire and co-workers embarked on experimental studies of topological insulators by investigating under what conditions the materials would generate higher harmonics of incoming laser light. This comes after having carried out such experiments on conventional insulators and semiconductors for about a decade. 2018-10-08 · Bandres, M. A. et al.
