A few days ago, the SOI Task Force of the State Key Laboratory of Information Functional Materials of Shanghai Microsystems Institute made a breakthrough in photonics research. The research results were published on PhysicalReviewLetters, published on May 20th, 2011, and they are the highlights of each session of PhysicalReviewLetters. One was selected as Editors' Suggest. This work has attracted extensive attention from international counterparts, the American Physical Society in physics. Aps. Org made a special report.
The on-chip manipulation of the beam has important theoretical significance and practical application value. Traditional optical theory holds that when the beam is bent, the radius of curvature of the path must not be less than the wavelength. Some researchers have proposed to use the near-field method such as surface plasmon polaritons and high-refractive-index particle arrays to overcome this limitation. For a propagating beam, more complex structures are needed to achieve this sub-wavelength deflection. The present study exploits the different symmetries of resonance modes of individual particles at resonance. After being aligned by a single layer consisting of only a few particles, the beam can be bent 90 degrees (zero curvature radius), and the curved light is The incident light is on the same side of the normal and negative refraction occurs.
The SOI task force of the State Key Laboratory of Functional Materials for Information Technology of the Shanghai Microsystems Institute is devoted to silicon-based photonics research such as silicon-based photonic devices, optoelectronic monolithic integration technologies, and silicon substrate photo-on-interconnection technologies. The research results published in PRL are expected to achieve important applications in high-density integrated silicon-based photonics and provide novel light manipulation principles for related research. This was the group's use of a standard CMOS process platform in March 2010. After the first development of a 10-Gbps silicon optical modulator chip in China, another major breakthrough in photonics research has been achieved.
The research results were funded by the Shanghai Municipal Science and Technology Commission, the Chinese Academy of Sciences, the National Development Fund Committee, the Ministry of Education, and the Ministry of Science and Technology.
