Grating Restricts Fiber Laser to Four Closely Spaced Lines

Facebook X LinkedIn Email
Output is switchable from one line to another, or two can lase simultaneously.

Breck Hitz

Wavelength-switchable fiber lasers are required for flexible dense-wavelength-division-multiplexing (DWDM) networks, as well as for many fiber optic sensing systems and for spectroscopic studies. Although researchers at several laboratories have used fiber Bragg gratings (FBGs) to tune a laser from one line to another, the spacing between the lines has been relatively large (i.e., several nanometers). In many cases, especially DWDM, tuning among closely spaced lines is highly desirable. Figure 1. Designed with four π-phase shifts, the FBG had a broad reflectance band that included...Read full article

    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.
    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...
