The results of this groundbreaking for the information of generation, transmission, processing, and provide opportunities to use the angular momentum of chip level on record, can also help scientists better understand the evolution and nature of a black hole

Tencent space - according to foreign media reports, an Australian research team created can be nanometer light control chip, this breakthrough invention paved the way for the next generation optical technology, also make possible further understanding human black holes. The research team in from Australia's royal Melbourne institute of technology professor Karl min ku (MinGu) under the guidance of design an integrated nano photonic chip, the chip of the angular momentum of light control reached an unprecedented high level. The results of this groundbreaking for the information on the generation, transmission, processing, and record using chip level provide opportunities, angular momentum can also help scientists better understand the evolution and nature of a black hole.

A beam of light in close to a straight line when they run around its axis of rotation and twist. Since the past few decades, scientists have for measuring the dynamic rotation angular momentum of light produced a great interest in study. Study is the use of the angular momentum of one of the major focus of the optical fiber is the possibility of large-scale expansion, this method is also called "reuse". However, because of does not exist in nature can feel the distortion of light material, thus realize chip level reuse angular momentum is still a major challenge. Professor gu said, their team on the photon chip design a series of fine pore size and nano groove, which was first used the chip to control distortion of light.

The design don't need any other mass optical material to detect the angular momentum of the signal. , he argues, the discovery opened including ultra hd display, high capacity optical communication and optical encryption security, truly compression chip application of angular momentum, also can be extended to describe the performance characteristics of the angular momentum of gravitational waves, has helped scientists get black hole more information interaction, to uncover the mysteries of the universe black hole.

Sweeney, the doctoral candidate at the university of science and technology hao-ran ren (HaoranRen), said the optical data signal is sent to the photon chip, know the destination for the data transfer is very important, otherwise the information will be lost. And specially designed nano photonic chip can accurately guide the angular momentum of data signals, make them in different transmission modes nano annular aperture transmit without losing any information.
