Silicon nanospheres amplify second-harmonic generation from monolayer semiconductors over 40-fold while retaining ...

A research team has demonstrated that silicon nanospheres can strongly enhance second-harmonic generation (SHG) from an ...

Fig. 1. (a) THz optical path diagram based on metasurface. By controlling the phase delays of LCP and RCP waves by unit cells, metasurface can transmit the LCP and RCP components of the incident ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240076 , discusses spin-controlled generation of a complete polarization set with randomly-interleaved plasmonic metasurfaces.

(Nanowerk Spotlight) In their pursuit of device miniaturization, researchers are exploring the untapped potential of two-dimensional materials. These atomically thin crystals, with their unique ...

Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images. Yet controlling these properties independently ...
