Ten years ago, three teams experimentally demonstrated the first spasers, or plasmonic
nanolasers, after the spaser concept was first proposed theoretically in 2003. An overview of …

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 …

Small lasers have dimensions or modes sizes close to or smaller than the wavelength of
emitted light. In recent years there has been significant progress towards reducing the size …

Optical metamaterials and nanoplasmonics bridge the gap between conventional optics and
the nanoworld. Exciting and technologically important capabilities range from …

The effects of cavity quantum electrodynamics (QED), caused by the interaction of matter
and the electromagnetic field in subwavelength resonant structures, have been the subject …

Spin-momentum locking is a direct consequence of bulk topological order and provides a
basic concept to control a carrier's spin and charge flow for new exotic phenomena in …

Plasmon lasers are a new class of coherent optical amplifiersthat generate and sustain light
well below its diffraction limit,,,. Their intense, coherent and confined optical fields can …

Semiconductor lasers, an important subfield of semiconductor photonics, have
fundamentally changed many aspects of our lives and enabled many technologies since …

The integration of optical interconnects with silicon-based electronics can address the
growing limitations facing chip-scale data transport as microprocessors become …

The plasmonic nanolaser is a class of lasers with the physical dimensions free from the
optical diffraction limit. In the past decade, progress in performance, applications, and …
