Two-dimensional plasmonic waveguides for nanolasing and four-wave mixing
New Journal of Physics, 2019 Plasmonic waveguides are an essential element of nanoscale coherent sources, including nanolasers and four-wave mixing (FWM) devices. Here we report how the design of the plasmonic waveguide needs to be guided by the ultimate application.

Superresolution four-wave mixing microscopy
Optics Express, 2012 We report on the development of a superresolution four-wave mixing microscope with spatial resolution approaching 130 nm which represents better than twice the diffraction limit at 800 nm while retaining the ability to acquire materials- and chemical- specific contrast.
