Optical Nanoprobe Spectroscopy and Imaging

Conventional optical microscopy techniques, even in super-resolution, are limited in spectroscopic image content, as desired for the study of functional molecular and quantum materials. In recent years, a range of novel optical imaging concepts have emerged based on optical nano-probes, near-field coupling, nonlinear interactions, light localization, beam shaping and confinement, dynamic scattering, or quantum light interaction, providing sub-diffraction imaging with spectroscopic contrast.

This APL Special Topic solicits letter publications on leading developments in this field, including original work in theory and experiment, as well as perspectives in method development and their ground-breaking applications in surface and material science, nano-photonics, molecular imaging, and many more.
