Area of Science:

  • Physics and Nanotechnology
  • Nanoplasmonics

Background:

  • Nanoplasmonics, focusing on nanoscale plasmonic effects, has vast applications but is limited by the lack of coherent plasmon field generators.
  • A 'spaser' (stimulated plasmon amplification by stimulated emission of radiation) was proposed to generate coherent surface plasmons, analogous to lasers generating coherent photons.
  • Realizing a spaser is challenging due to significant optical absorption losses in metals, especially at optical frequencies.

Purpose of the Study:

  • To overcome the absorption loss challenge in metal nanostructures for spaser realization.
  • To demonstrate a functional spaser capable of generating coherent surface plasmon fields.
  • To develop the smallest nanolaser operating at visible wavelengths.

Main Methods:

  • Utilizing 44-nm-diameter nanoparticles with a gold core and a dye-doped silica shell.
