Chinese scientists have made new progress in the field of polarization stress

Xinhua News Agency, Beijing, August 19 (Reporters Dong Ruifeng and Zhang Quan) How can they better control the light in the micro world and make communication and imaging technologies a new leap? A scientific research team in my country has achieved the latest progress through international cooperation, and it is expected to achieve precise control of nano -scale light and improve the level of application levels such as nano -level photoelectric interconnection and optical sensing. The research results were published online by the international academic journal "Nature Nano -Technologies".

Polarization stimulus is a special electromagnetic mode formed by interaction between light and material surface interface. It can also be regarded as a quasi -particle formed by a photon and material coupling. It has excellent light field compression capabilities and can easily break through the optical diffraction limit to achieve the transmission and processing of light information on nano -scale.

Dai Qing, one of the author of the thesis communication and researcher at the National Nano Science Center, introduced that the research team cleverly designed graphene/α phase molybdenum oxide heterogeneous knots and combined with unique chemical doping methods. Topology changes in equivalent outlines not only make the transmission direction break through the restrictions of the original crystal direction, but also can converge energy efficiently for directional low -loss transmission.

"In general, our research work is to compress the infrared light of 10 microns to one thousandths and then regulate, and it must be passed far and moved." Dai Qing said, "For example, we must not only make the bigger big Elephant in a chalk box also drives the elephant to move freely inside. "

In the early research work, Dai Qing's research team developed the method of high -efficiency mixed graphene in gas molecularly, maintaining the longest transmission distance of graphene leaving tone at room temperature.

Micro -nano -optical is one of the active forefronts of the development of optical disciplines, and it is also an important development direction of the new optoelectronics industry. Micro -nano optical components can achieve many new functions based on local electromagnetic interactions, so it plays an important role in the fields of optical communication, interconnection, storage, sensing, and imaging.

It is reported that the above research results will provide new ways to further control the directional communication and energy convergence of electromagnetic waves, and also provide new ideas for designing nano -optoelectronic interconnect chips.
