In-plane illuminated metallic annular aperture array for sensing application.
نویسندگان
چکیده
We propose here an application to sensing of annular aperture arrays (AAA). We theoretically investigate the optical properties of the reflective AAA device when illuminated in-plane. The cavity presents almost perfect absorption due to the waveguide mode resonance with strong field localization in the aperture. Additionally, the reflective cavity is modeled to be available for on-chip sensing with a theoretically expected sensitivity of 764 nm/RIU(refractive index unit).

Aberrated Edge imaging with annular apertures
In this paper, we have studied the aberrated images of coherently illuminated straight edge objects with annular aperture in the presence of apodisation. The analytical studies were made for annular apertures apodised with Shaded aperture under the influence of defocus and primary spherical aberrations. The effect of aperture obscuration and apodisation on the edge ringing and peak intensity ha...

متن کاملGeneration of multiple vortex-cones by direct-phase modulation of annular aperture array.
The generation of multiple vortex cones using an annular aperture array and a spatial light modulator (SLM) is studied. The direct downscale imaging of an SLM on the surface of an annular aperture enables the direct-phase modulation of the annular aperture. It is experimentally demonstrated that the direct-phase modulation of an annular aperture array can control both the topological charge and...
متن کاملPupil plane multiplexing for multi-domain imaging sensors
We describe an approach to polarimetric imaging based on a unique folded imaging system with an annular aperture. The novelty of this approach lies in the system’s collection architecture, which segments the pupil plane to measure the individual polarimetric components contributing to the Stokes vectors. Conventional approaches rely on time sequential measurements (time-multiplexed) using a con...
متن کاملField enhancement in metallic subwavelength aperture arrays probed by erbium upconversion luminescence.
Upconversion luminescence from erbium ions placed in the near field of subwavelength aperture arrays is used to investigate field enhancement of incident near-infrared light in such nanostructures. We study field enhancement due to the excitation of both propagating and localized surface plasmon resonances in arrays of square and annular apertures in a Au film. The conversion of 1480 nm excitat...
