Kurzbeschreibung
(Englisch)
|
PhCs have been the focus of extensive research due to their ability to control both light propagation and localization at the wavelength scale. The need for more advanced optical characterisation tools has emerged with the integration of PhC devices in complex integrated optics systems and with the development of more advanced concepts. Such PhC structures request a refined investigation of light propagation phenomenology and the knowledge of its associated physical characteristics. The aim of the project is to use high numerical aperture real space and Fourier space imaging techniques for the investigation of photonic crystals nanostructures. The project has two aspects. The first aspect concerns the development of the set-up and of the experimental techniques of analysis in order to push the performance up to the fundamental limits of classical optics. It will notably includes i) the possibiliy to perform spatial or Fourier filtering in an intermediate image plane while performing the dual-type imaging observation and ii) the adjunction of local excitation probe beam for the local excitation of light emitter or local tuning functionality. The set-up will be designed for operation at several wavelengths ranges around 980 nm, 1.3 and 1.55µm. The second aspect concern the use of such sep-up on three demonstrator test structures each of them involving a different concept among the present-day hot topics in PhC, namely: 1) Self collimating structures, 2) High Q cavities and 3) Slow light structures. The structures will be designed, fabricated and then measured within the project.
