The angular emission of light of wavelength 710 and 810 nm from a gold diffraction grating was studied at about 700 o C. A peak in the emission was found for defined angles. This contribution is purely TM-polarised and is attributed to thermally excited surface plasmons, coupled to light waves by the diffraction grating.
Scattering optical waveguide microscopy is introduced as a novel imaging technique, that allows for the microscopic characterization of thin film samples by using the evanescent field of a guided optical wave as the illuminating light source. The image contrast is generated by the scattering intensity of the thin film sample within the evanescent field. Excellent lateral resolution (< 1 μm) is...
