Widespread Application

Fiber Bragg gratings have found widespread application in sensor systems, e. g. for temperature, strain or refractive index measurements. The concept of fiber Bragg gratings allows also in a simple way the realisation of arrays of such sensors. The development of such optical fiber sensor systems often requires special fibers and grating structures which may go beyond more conventional Bragg grating structures in typical communication fibers. Concerning fibers there is, for example., a need of achieving fiber gratings in small diameter fibers and fiber tapers as well as in microstructured fibers. Special fiber grating structures are of interest e.g. in the visible wavelength range, which requires smaller spatial structures compared to more conventional gratings in the near infrared wavelength region. Examples for such modern developments in fiber Bragg grating technology for sensor applications will be presented and discussed.

Far Field Pattern

We propose a novel plasmon nano-optical antenna that consists of three vertically superimposed discs with different materials. Two symmetrical nanometer-scale Yagi antenna elements with gold-material are embedded into the surface of the middle disc with silicon dioxide. Based on plasmon theory and Yagi antenna principle, we explore the properties of the far-field radiation and near-field transmission of the antenna in near infrared band. It is found that the pattern of the xoy plane in the antenna can be adjusted in arbitrary direction. The far-field pattern and near-field transmission spectrum can be reconfigured by changing the angle a of the Yagi antenna elements in the middle disc. Moreover, we also discuss the influences of the widths and lengths of the elements on the near-field transmission spectrum when a is fixed at 0 degree.
