Visualizing the whispering gallery modes in a cylindrical optical microcavity [PDF]
, 1999 Whispering gallery modes in cylindrical integrated optics microcavities have, for what is to our knowledge the first time, been mapped with a photon scanning tunneling microscope. Optical images were obtained with a spatial resolution of 50 nm.

Whispering gallery modes in semiconductor optical fibres and optical bottle microresonators
We explore the optical properties of whispering gallery modes (WGMs) in silicon optical fibres and optical bottle microresonators. In particular, a pump-probe technique is used to experimentally demonstrate thermally induced all-optical modulation.

Photochemical fluorescence activation in arrays of microspherical containers
Responsive Materials, EarlyView.Photoresponsive microdroplets can be produced with precise structural control from organic solutions of a photoactivatable fluorophore and aqueous solutions of a surfactant at a microfluidic cross junction. These dye‐doped microspheres assemble spontaneously in close‐packed arrays in aqueous media.
