Researchers created a microscopic, nonlinear light source that can be switched on, off or tuned to a particular intensity by an electrical 'knob'. The device is just 200 nanometers wide and has a controllable active area of two-to-six nanometers, enabling faster and more efficient optical switching.
The researchers created a novel method for using cholesteric liquid crystals in optical microcavities, enabling the formation and dynamic tuning of photonic crystals. This breakthrough research has the potential to revolutionize photonic engineering by opening up new perspectives in the manipulation of light.
A research team at POSTECH developed a metasurface technology that can display multiple high-resolution images on a single screen, overcoming conventional holographic limitations. The innovation uses nanostructure pillars to precisely manipulate light, allowing for different images based on wavelength and polarization direction.
Researchers at TMOS have developed a new infrared filter thinner than cling wrap, which can be integrated into everyday eyewear, allowing users to view both visible and infrared light spectra. This breakthrough miniaturizes night vision technology, opening up new applications in safety, surveillance, and biology.
A Princeton University study reveals a type of foam can block specific wavelengths of light while allowing others to pass through, creating a photonic band gap. This property has the potential to control the flow of electrons in materials and could lead to breakthroughs in telecommunications.
A team of researchers led by Weining Man has developed a two-dimensional disordered photonic band gap material that can manipulate the flow and radiation of light. The material breaks away from traditional photonic crystals, allowing for arbitrarily shaped paths to steer light.
