A new type of non-mechanical beam steering device, based on liquid crystal (LC) cladding waveguide, is the Steerable Electro-Evanescent Optical Refractor (SEEOR), which has attracted widespread attention due to its large angle, continuous steering, and fast response time. However, a comprehensive theory on how to design SEEOR coupling structures with high coupling efficiency is still unclear.
Amer Kotb from Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences (CAS) and his co-authors, Kyriakos Zoiros from the Democritus University of Thrace, Antonios Hatziefremidis from National Kapodistrian University of Athens, and Chunlei Guo from the Institute of Optics, University of Rochester, Rochester, have employed Z-shaped silicon-on-silica waveguide to demonstrate AOLGs, including XOR, AND, OR, NOT, NOR, NAND, and XNOR, that operate at 1.55 μm.
In a study published in Biosensors and Bioelectronics, a research group led by WU Yihui from Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences (CAS) proposed multistage microfluidic cell sorting method and chip based on size and stiffness.
In a study published in Advanced Optical Materials, researchers from Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences (CAS) have systematically investigated the second harmonic generation (SHG) in mechanically exfoliated, few-layer ReS2 samples which is strongly dependent on stacking order, layer number, fundamental photon energy, and light polarization.
The high field confinement in silicon core combined with superior miniaturization and low loss are some of the key features of using silicon waveguides for realizing integrated optical components. In addition, silicon has the best crystal quality and is the least expensive of all semiconductor materials.
In a study published in Optics Letters, a research group led by Prof. LI Wei from Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), Chinese Academy of Sciences (CAS) has shown that the nano-mechanical dynamics of water surfaces can be measured quantitatively by observing the interplay between optics and fluid mechanics.
