Efficient metallic spintronic emitters of ultrabroadband terahertz radiation

, 2016
Terahertz electromagnetic radiation is extremely useful for numerous applications such as imaging and spectroscopy. Therefore, it is highly desirable to have an efficient table-top emitter covering the 1-to-30-THz window whilst being driven by a low-cost,

A flexible eye-safe lidar instrument for elastic-backscatter and DIAL [PDF]

, 2012
Developments in lidar have been driven largely by improvements in two key technologies: lasers and detectors. We describe here a lidar instrument for atmospheric remote sensing using the elastic-backscatter and differential-absorption lidar (DIAL ...

All-optical intensity noise suppression for solid-state and semiconductor lasers

Journal of Telecommunications and Information Technology, 2005
This paper will report on a new all-optical technique of relative intensity noise (RIN) suppression for solidstate and semiconductor lasers. The new scheme we have used is based on an unbalanced Mach-Zehnder interferometer (UMZI), which is able to ...
