(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

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) . This laser was constructed on a standard optoelectronic platform, as an aperiodic array of 10 × 10 coupled ring-resonators on InGaAsP quantum wells wafer. 2020-12-22 · Harari, G. et al.

• Due to the spin texture, back scattering is still forbidden. 2013-01-01 2020-03-01 Topological insulators (TIs), are novel two-dimension materials, which can act as effective saturable absorbers (SAs) in a fiber laser. Moreover, based on the evanescent wave interaction, deposition of the TI on microfiber would create an effective SA, which has combined advantages from the strong nonlinear optical response in TI material together with the sufficiently-long-range interaction Topological insulator laser: Experiments.

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. We show that this system is uniquely

These contain what is in effect a knot, making it impossible to smoothly convert a topological insulator into a normal insulator. A new hands-off probe uses light to explore electron behavior in a topological insulator Just as pressing a guitar string produces a higher pitch, sending laser light through a material can shift Topological insulators are one of the most puzzling quantum materials—a class of materials whose electrons cooperate in surprising ways to produce unexpected properties. The edges of a TI are tion of an EM topological insulator [8], and seven years after the ﬁrst observation of the ﬁrst photonic topological insulators [12, 15]. These experiments, and the pioneering theoretical papers during those ﬁrst years, have created a new area from scratch: Topological Photonics.
