We present a regrowth and grating free InP-based single-facet teardrop laser consisting of a 1×2 multi-mode-interferometer and a waveguide loop reflector. The fabricated laser demonstrated CW lasing ...

Terahertz radiation (THz), electromagnetic radiation with frequencies ranging between 0.1 and 10 THz, could be leveraged to ...

GaN-based laser diodes (LDs) with different barrier layers are investigated by using simulation and experimental methods. it is found that the absorption loss always decreases with the increasing ...

We report the experimental demonstration of an optically pumped silver-nanopan plasmonic laser with a subwavelength mode volume of 0.56(λ/2n)3. The lasing mode is clearly identified as a ...

Recent studies have demonstrated the applicability of the “single particle” mode in laser ablation–inductively coupled plasma–mass spectrometry to map and size particles simultaneously. The transport ...
