Topological-insulator-based terahertz modulator
Xinbo Wang,Liang Cheng,Yang Wu,Dapeng Zhu,Lan Wang,Jian-Xin Zhu,Hyunsoo Yang,Elbert E. M. Chia +7 more
TL;DR: This work experimentally demonstrates an electronically-tunable terahertz intensity modulator based on Bi1:5Sb0:5Te1:8Se1:2 single crystal, one of the most insulating topological insulators, and proposes that the extraordinarily large modulation is a consequence of thermally-activated carrier absorption in the semiconducting bulk states.

TL;DR: A monolithic terahertz injection laser that is based on interminiband transitions in the conduction band of a semiconductor (GaAs/AlGaAs) heterostructure is reported, which is very promising for extending the present laser concept to continuous-wave and high-temperature operation, which would lead to implementation in practical photonic systems.
