Stirring Up a Passion for Photonics

SAN FRANCISCO, Jan. 24, 2010 — It rather stands out among the shiny high-tech devices strung along the aisles at the BiOS trade exhibition — a simple pine valise propped open at one of the tables belonging to Omega Optical. Rough-hewn by comparison with the colorful, glossy filters and other optical components the company has brought to showcase, the box reminds passersby of the Vermont countryside outside the windows of Omega’s Brattleboro headquarters. A glance inside, though, quickly shows that there’s a tale to tell: Poking out at all angles is an assortment of light sources, meters, optical...Read full article

    absorption
    Absorption is the process by which a material takes in energy from electromagnetic radiation (such as light, heat, or sound) and converts it to other forms of energy, typically internal energy (such as heat). This process occurs when the energy of the incident radiation is transferred to the atoms or molecules of the absorbing material, causing them to increase in vibrational, rotational, or electronic energy levels. In different contexts, absorption can refer to: Physics and optics:...
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    polarization
    Polarization refers to the orientation of oscillations in a transverse wave, such as light waves, radio waves, or other electromagnetic waves. In simpler terms, it describes the direction in which the electric field vector of a wave vibrates. Understanding polarization is important in various fields, including optics, telecommunications, and physics. Key points about polarization: Transverse waves: Polarization is a concept associated with transverse waves, where the oscillations occur...
    reflection
    Return of radiation by a surface, without change in wavelength. The reflection may be specular, from a smooth surface; diffuse, from a rough surface or from within the specimen; or mixed, a combination of the two.
    refraction
    The bending of oblique incident rays as they pass from a medium having one refractive index into a medium with a different refractive index.
