The different patterns of the two photonic crystals gave rise to a one-way, robust photonic edge state, much like the electronic edge states in a topological insulator.

As a direct consequence of the topological order, of experiments are the first to establish the 3D topological order, Such a laser implements a resonating mode that is intrinsically protected, thanks to the topological properties of its architecture, against external perturbations and fabrication defects. The discovery of topological phase transitions in condensed matter, which was awarded the 2016 Noble prize in physics, has profoundly influenced the field of solid-state physics. A similar idea underpins topological insulators, but the transformation in this case doesn’t involve a material’s spatial properties.

Now scientists have discovered how to use this phenomenon to explore quantum materials in a new and much more detailed way. Now, a pair of papers from a research group in Israel and the United States report the design and demonstration of a semiconductor laser based on topological-insulator principles (Science, doi: 10.1126/science.aar4003, 10.1126/science.aar4005).

The proposed system is realized as a truncated array of lasing helical waveguides, where the pseudomagnetic field arises due to twisting of the waveguides along the propagation direction that breaks the time-reversal symmetry and opens up a topological gap. Laser-based Angle-resolved Photoemission Spectroscopy of Topological Insulators Abstract Topological insulators (TI) are a new phase of matter with very exotic electronic properties on their surface. As a direct consequence of the topological order, of experiments are the first to establish the 3D topological order, Such a laser implements a resonating mode that is intrinsically protected, thanks to the topological properties of its architecture, against external perturbations and fabrication defects.

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 Ferromagnetic topological insulators (TIs) have promise for applications in spintronics, metrology, and quantum computing. However, TI materials are fragile and often incompatible with nanofabrication techniques. Here, we demonstrate persistent, micron-scale optical control of both magnetization and chemical potential in Cr-(Bi,Sb)2Te3 grown on SrTiO3.
