The Institute of Semiconductors, Chinese Academy of Sciences has made new progress in opto-mechanical coupling research
From the micro-net news, the team of researcher Jun Zhang from the State Key Laboratory of Semiconductor Superlattices, Institute of Semiconductors, Chinese Academy of Sciences has made new progress in the study of optical-mechanical coupling and was invited by Nanoscale magazine to publish a "Topology-Based Original paper (Terahertz cavity optomechanics using a topological nanophononic superlattice)" and "Review: From cavity optomechanics to cavityless exciton optomechanics" -less exciton optomechanics: a review).
In this work, the team of researcher Jun Zhang introduced nanophononic topological interface state into the optomechanical system, and used the finite element calculation method to design a semiconductor microstructure of terahertz mechanical frequency based on GaAs/AlAs nanophonon superlattice. Cavity optomechanical device. On August 17, 2022, the research results were published online in Nanoscale, (2022), 14, titled "Terahertz cavity optomechanics using a topological nanophononic superlattice". On 13046-13052, researcher Zhang Jun is the corresponding author, and master student Chang Haonan is the first author. The collaborators include Dr. Yao Qifeng from Beijing Institute of Quantum Information, Dr. Liu Bin from Nanjing Guoke Semiconductor Corporation, and researcher Lou Wenkai from the Institute of Semiconductors, Chinese Academy of Sciences. Researcher Ni Haiqiao, Researcher Niu Zhichuan, and Academician Chang Kai.
Zhang Jun's team used the Fröhlich force generated by light on longitudinal optical (LO) phonons under the strong coupling of phonon-excitons to achieve the resolution of a single longitudinal optical (LO) phonon in a semiconductor ZnTe nanoribbon in 2016. Sideband Raman cooling and heating, demonstrating that the optical manipulation of single optical phonon states in semiconductors is fully achievable under strong exciton-phonon coupling (Nature Photonics 10, 600–605 (2016)); Laser cooling of single optical phonons was achieved in two-dimensional van der Waals crystals (Nano Lett. 22, 7129–7135 (2022)). Recently, Zhang Jun's team wrote a review paper on cavityless exciton opto-mechanical coupling. This review systematically describes the development trend of optodynamic devices from "cavity" to "cavityless", which is of great reference value for scientific researchers and technicians engaged in the research and application of optomechanics. September 23, 2022, published online in Nanoscale (2022) DOI: 10.1039 under the title "From cavity optomechanics to cavity-less exciton optomechanics: a review" On /D2NR03784J, researcher Zhang Jun is the corresponding author, and master student Chang Haonan is the first author.
