Purpose Kretschmann-configuration has been used as a subwavelength framework to
detect tiny‎ alterations of the refractive index of biomaterials. However, most of the theoretical …

We investigate the usefulness of the wide-angle Fast Fourier Transform-based beam
propagation method (FFT-BPM) to investigate important and quite involved problems in the …

We describe a controllable infrared plasmonic laser attenuator with application to infrared
detector characterization. The device promises a broad range of effective radiant …

We describe two designs for a variable attenuator of infrared laser radiation. The principle is
based on the excitation of surface plasmon polaritons with prism couplers on suitable …

We adapted the traditional FFT-BPM to assess the performance of plasmonic waveguide as
biosensor. The tightly confined optical power in such waveguide enables an efficient way to …

An infrared attenuator includes a prism having a first conductive element at a surface thereof
and a second conductive element at an adjustable distance from the first conductive …
