ATLANTA, Dec. 8, 2010 — A new class of sensors able to detect multiple biological and chemical threats simultaneously with unprecedented performance may soon be within reach, thanks to the establishment of a multimillion-dollar research center led by Georgia Institute of Technology engineers. Georgia Institute of Technology’s Ali Adibi, a professor in the School of Electrical and Computer Engineering, will lead the new Center in Integrated Photonics Engineering Research (CiPhER) that DARPA is establishing at the institute.

    Glossary
    absorption
    The transfer of energy from an incident electromagnetic energy field with wavelength or frequency to an atomic or molecular medium.
    fluorescence
    Fluorescence is a type of luminescence, which is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Specifically, fluorescence involves the absorption of light at one wavelength and the subsequent re-emission of light at a longer wavelength. The emitted light occurs almost instantaneously and ceases when the excitation light source is removed. Key characteristics of fluorescence include: Excitation and emission wavelengths: Fluorescent materials...
    integrated photonics
    Integrated photonics is a field of study and technology that involves the integration of optical components, such as lasers, modulators, detectors, and waveguides, on a single chip or substrate. The goal of integrated photonics is to miniaturize and consolidate optical elements in a manner similar to the integration of electronic components on a microchip in traditional integrated circuits. Key aspects of integrated photonics include: Miniaturization: Integrated photonics aims to reduce the...
    multiplexing
    The combination of two or more signals for transmission along a single wire, path or carrier. In most optical communication systems this is referred to as wavelength division multiplexing, in which the combination of different signals for transmission are imbedded in multiple wavelengths over a single optical channel. The optical channel is a fiber optic cable or any other standard optical waveguide.
    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.
    polymer
    Polymers are large molecules composed of repeating structural units called monomers. These monomers are chemically bonded together to form long chains or networks, creating a macromolecular structure. The process of linking monomers together is known as polymerization. Polymers can be classified into several categories based on their structure, properties, and mode of synthesis. Some common types of polymers include: Synthetic polymers: These are human-made polymers produced through...
    sensor
    1. A generic term for detector. 2. A complete optical/mechanical/electronic system that contains some form of radiation detector.
    spectrometer
    A kind of spectrograph in which some form of detector, other than a photographic film, is used to measure the distribution of radiation in a particular wavelength region.
