Flat optics has emerged as a key player in the area of structured light and its applications,
owing to its subwavelength resolution, ease of integration, and compact footprint. Although …

Metasurfaces are ultrathin metamaterials consisting of planar electromagnetic (EM)
microstructures (eg, meta-atoms) with pre-determined EM responses arranged in specific …

The highest possible resolution for printed colour images is determined by the diffraction
limit of visible light. To achieve this limit, individual colour elements (or pixels) with a pitch of …

This review provides a perspective on the recent developments in the transmission of light
through subwavelength apertures in metal films. The main focus is on the phenomenon of …

We show that short-pulse laser-induced classical ripples on dielectrics, semiconductors, and
conductors exhibit a prominent “non-classical” characteristic in normal incidence the …

Metallic nanostructures now play an important role in many applications. In particular, for the
emerging fields of plasmonics and nanophotonics, the ability to engineer metals on …

Recent developments in color filtering and display technologies have focused
predominantly on high resolution, color vibrancy, high efficiency, and slim dimensions. To …

In recent years, nanoplasmonic sensors have become widely used for the label-free
detection of biomolecules across medical, biotechnology, and environmental science …

We introduce an ultrasensitive label-free detection technique based on asymmetric Fano
resonances in plasmonic nanoholes with far reaching implications for point-of-care …

Tunable narrowband spectral filtering across arbitrary optical wavebands is highly desirable
in a plethora of applications, from chemical sensing and hyperspectral imaging to infrared …
