The acousto-optic modulation over a broad near-infrared (NIR) spectrum with high speed, excellent integrability, and relatively simple scheme is crucial for the application of next-generation opto-electronic and photonic devices. This study aims to experimentally demonstrate ultrafast acousto-optic phenomena in the broad NIR spectral range of 0.77-1.

In the development of new organic crystals for nonlinear optical and terahertz (THz) applications, it is very challenging to achieve the essentially required non-centrosymmetric molecular arrangement. Moreover, the resulting crystal structure is mostly unpredictable due to highly dipolar molecular components with complex functional substituents. In this work, new organic salt crystals with top-level macroscopic optical nonlinearity by controlling the van der Waals volume (V ), rather than by trial and error, are logically designed.

Unlabelled: The rapid expansion of virtual reality (VR) and augmented reality (AR) into various applications has increased the demand for hands-free input interfaces when traditional control methods are inapplicable (e.g., for paralyzed individuals who cannot move their hands).

Article Synopsis
  • Omicron has become the main strain of SARS-CoV-2, making it harder to neutralize despite previous infections or two-dose vaccines.
  • A three-dose mRNA vaccine better boosts neutralizing antibodies and provides longer-lasting protection against various SARS-CoV-2 variants, though levels against Omicron are still low.
  • Individuals who experience an Omicron breakthrough infection after three doses see an increase in neutralizing antibodies and T cell responses, which may enhance immunity against new SARS-CoV-2 variants.
