We report plasmon lasers with strong cavity feedback and optical confinement to 1/20th wavelength. Strong feedback arises from total internal reflection of plasmons, while confinement enhances the spontaneous emission rate by up to 20 times.
Based on a hybrid-plasmon (HPP) platform, we report the first demonstrations of low-loss, deep-subwavelength waveguiding and plasmon semiconductor Nanolaser with room temperature operating, towards wavelength-scale photonic integrated circuits.

We review recent progress on metal-based lasers with optical confinement approaching 1/20th of the wavelength at room temperature and discusses the broader impact of plasmonic light sources and their application.
We report plasmon lasers with optical confinement of 1/20th wavelength operating at room temperature. The strong confinement and efficient feedback arising from plasmonic total internal reflection enhance the spontaneous emission rate up to 20 times.
This paper reports a miniature MEMS tunable dual-wavelength laser by integrating a gain chip, a beam splitter, and a pair of Bragg reflectors which has different periods. In the experiment, simultaneous two wavelengths emissions are observed with a thermo-optic tuning range of 1574.7 nm to 1578.6 nm and 1576.1 nm to 1582.6 nm, respectively.
The PANDA experiment at the new FAIR facility in Darmstadt, Germany, will be investigating unresolved questions of non-perturbative QCD. The experiment is designed to make use of internal targets in the p storage ring HESR (design luminosity: 2 . 1032 cm-2 s-1, pp-annihilation rate: 2 . 107 s-1), requiring continuous operation of all detectors. One option for its central tracking unit is a Time Projection...
We demonstrate that using longer-wavelength driving light in high-order harmonic generation requires moderately ionized larger-density atoms to perfectly phase match the process, scaling conventional phase matching at low ionization to extremely high photon energies.
An experimental determination of the linewidth enhancement factor, alpha, of a GaInNAs/GaAs laser is presented. The modal gain and Fabry-Perot mode shift with injection current were analysed to derive a value of alpha=2.8 at threshold for the 1278 nm emission
