Nanolasers generate coherent light at the nanoscale. In the past decade, they have attracted intense interest, because they are more compact, faster and more power-efficient than conventional lasers. Thanks to these capabilities, nanolasers are now an emergent tool for a variety of practical applications. In this Review, we explain the intrinsic merits

2018 International Conference on Optical MEMS and Nanophotonics (OMN), 2018
We propose and demonstrate a direct integration of a III-V nanolaser onto a silicon waveguide. By employing high-precision micro-transfer printing techniques, with an optimally designed photonic crystal nanolaser cavity, we experimentally achieved a coupling efficiency of 83% between the InGaAsP nanobeam laser and the single-mode silicon waveguide ...

Self-polarized spin-nanolasers
Nature Nanotechnology, 2014Besides adding a new functionality to conventional lasers, spin-polarized lasers can, potentially, offer lower threshold currents and reach higher emission intensities. However, to achieve spin-polarized lasing emission a material should possess a slow spin relaxation and a high propensity to be injected with spin-polarized currents.

Recent Progress in Nanolaser Technology
Advanced Materials, 2020AbstractNanolasers are key elements in the implementation of optical integrated circuits owing to their low lasing thresholds, high energy efficiencies, and high modulation speeds. With the development of semiconductor wafer growth and nanofabrication techniques, various types of wavelength‐scale and subwavelength‐scale nanolasers have been proposed ...

Self-Assembled Dipole Nanolasers
Journal of the American Chemical Society, 2014Visible light excitation of silver nanoparticles in the presence of polymerizable monomers and selected dyes triggers the self-assembly of nanolasers in a synthetically simple process. The new nanolasers incorporate a thin, fully organic gain medium that allows the tuning of the core absorption to a selected dye, or of the dye to a preselected core ...
