Enhancing Sensitivity at Higher-Order Exceptional Points

Facebook X LinkedIn Email
ORLANDO, Fla., Sept. 1, 2017 — Active photonic molecule lasers that are non-uniformly pumped could provide a way to generate high sensitivity exceptional points in a systematic way. A research team at the University of Central Florida’s College of Optics & Photonics (CREOL) has demonstrated this concept. The team generated second order exceptional points using a coupled binary photonic molecule under parity-time symmetric conditions and extended this concept to higher-order exceptional points. The researchers generated a higher-order exceptional point by coupling three micro-rings made from a semiconductor laser...Read full article

    micro-optics
    Micro-optics refers to the design, fabrication, and application of optical components and systems at a microscale level. These components are miniaturized optical elements that manipulate light at a microscopic level, providing functionalities such as focusing, collimating, splitting, and shaping light beams. Micro-optics play a crucial role in various fields, including telecommunications, imaging systems, medical devices, sensors, and consumer electronics. Key points about micro-optics: ...
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
