Researchers from the GPL Photonics Laboratory at the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, together with the University of Chinese Academy of Sciences, reported a route to unpolarized nonreciprocal thermal emitters in the IEEE Journal of Selected Topics in Quantum Electronics. The work explains why nonreciprocity—traditionally restricted to a single polarization under the transverse magneto-optical Kerr effect (TMOKE)—can be achieved for both polarizations, and it demonstrates device designs that enhance nonreciprocal radiative heat transfer.
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, report self-powered far-UVC photodetectors based on cubic-phase MgZnO (c-MgZnO) in ACS Applied Materials & Interfaces. The team realized two device types—a Schottky junction and a PIN heterojunction—that operated at zero bias with nanosecond response and stable performance at high temperature.
Optics Communications, published by Elsevier, has released a study from the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, presenting a new method to design high-performance photonic devices for a promising material platform, thin-film lithium niobate on insulator (LNOI).
A study published in Scientific Reports by Springer Nature, with researchers from the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, introduced a novel method to significantly improve the clarity of images captured by aerial cameras. This approach addresses a persistent challenge in remote sensing: image blur caused by optical aberrations that vary unevenly across the field of view.
A study published in Advanced Materials by Wiley-VCH GmbH, with researchers from the Changchun University of Technology and the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, demonstrated a new method to significantly improve the performance and longevity of devices that generate electricity from atmospheric moisture. By integrating a light-sensitive component, the team created a device that overcomes a major limitation of conventional moisture electricity generators (MEGs).
A study published in Dalton Transactions by the Changchun Institute of Optics, Fine Mechanics and Physics and the Royal Society of Chemistry, with collaborators from Chongqing University of Posts and Telecommunications and, reports the creation of a new material that emits high-purity red light when excited by a specific type of near-infrared light. This advancement holds potential for improved temperature sensing deep inside biological tissues and for creating more secure anti-counterfeiting features.
