Imagine the benefits if the entire internet got a game-changing upgrade to speed and security. This is the promise of the quantum internet—an advanced system that uses single photons to operate. Researchers at Tohoku University ...
A research team has successfully developed a self-locked Raman-electro-optic (REO) microcomb on a single lithium niobate chip. By synergistically harnessing the electro-optic (EO), Kerr, and Raman effects within one microresonator, ...
Excitons, bound states between an electron (i.e., a negatively charged particle) and a hole (i.e., the absence of an electron) in materials, are a key focus of condensed matter physics studies. These bound states can give ...
A new study has successfully demonstrated the confinement of terahertz (THz) light to nanoscale dimensions using a new type of layered material. This could lead to improvements in optoelectronic devices such as infrared emitters ...
A photonics research group co-led by Gregor Weihs of the University of Innsbruck has developed a new technique for generating multi-photon states from quantum dots that overcomes the limitations of conventional approaches. ...
As technology advances, photonic systems are gaining ground over traditional electronics, using light to transmit and process information more efficiently. One such optical system is laser beam scanning (LBS), where laser ...
Colloidal halide perovskite nanocrystals have emerged as strong candidates for light-emitting diodes and solar applications due to their excellent photoluminescent properties. However, instability and lead toxicity limit ...
Resonantly tunable quantum cascade lasers (QCLs) are high-performance laser light sources for a wide range of spectroscopy applications in the mid-infrared (MIR) range. Their high brilliance enables minimal measurement times ...
Konstantin Vodopyanov, a professor at the College of Sciences and CREOL, the College of Optics and Photonics, recently co-authored a study published in the journal Optica. This research examines electro-optic sampling (EOS), ...
In recent research published in Optics & Laser Technology and Infrared Physics & Technology, a research team led by Prof. Cheng Tingqing at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has introduced ...
