  • Publication number: 20060274314
    Abstract: An evanescent field microscopy sub-unit for an examination system for examination of a specimen, the evanescent field microscopy sub-unit includes a first dielectric cladding layer having an absolute refractive index n1, and a core layer having a thickness tm, a width wm and a length Im coated onto at least a part of said first cladding layer, the evanescent field microscopy sub unit being arranged to support a specimen to form a part or all of a second cladding on the side of the core layer opposite the first cladding layer.

  • Patent number: 6782179
    Abstract: The present invention provides a method and devices for controlling the propagation of Surface Plasmon Polaritons (SPPs) using Surface Plasmon Polariton Band Gap (SPPBG) regions. The SPPBG regions are regions of one or more interfaces supporting the propagation of SPPs on which SPPs experience a periodic modulation of the dielectric properties of the media into which its electromagnetic field extend. The frequency range of the band gap is determined by the period of the modulation. SPPBG regions prohibit propagation of SPPs having a frequency within its band gap. By forming transmitting regions in the SPPBG regions the present invention provides ultra-compact SPP waveguides. The present invention can be utilised to form compact integrated SPP/optical circuits. Also, the present invention provides cavities supporting standing SPP-waves for field localisation. Such field localisation can provide very high field intensities and can be used in various sensor applications.

  • Publication number: 20030133681
    Abstract: The invention provides a waveguiding device and a method for guiding electromagnetic (EM) waves, in particular surface plasmon polaritons (SPPs), using strongly scattering random media exhibiting light localization. Also, the invention provides a cavity for providing resonance conditions for EM waves, in particular surface plasmon polaritons using strongly scattering random media exhibiting light localization. In a strongly scattering random medium with a high enough density of scatterers (so that the average distance between scatterers is smaller than the wavelength), EM waves can only exist in localized modes and can therefore not propagate. By forming regions free from scatterers in the regions with randomly distributed scatterers, the localization effects in scattering media can be utilized to guide propagating modes in these regions. The invention can be used to form compact integrated optical components and circuits.
