Stacked subwavelength gratings as circular polarization filters.
We have stacked subwavelength gratings (SWGs) on a single substrate to create a compact, integrated circular polarization filter. The SWGs consist of a wire grid polarizer and a broadband form-birefringent quarter-wave plate (QWP). Rigorous coupled-wave analysis was used to design the QWP for operation over the 3.5-5.0-mum wavelength range. The fabricated silicon broadband QWP exhibited a phase...
متن کاملAnalysis of stacked rotated gratings.
We study the rigorous design and analysis of stacked rotated gratings (SRGs) for novel photonic devices. A concept of sampling frequency is proposed to systematically design SRGs. With the help of a rectangular sampling lattice, we extend the standard 3D rigorous coupled-wave analysis (RCWA) algorithm to the analysis of SRGs. The resultant SRG-RCWA algorithm can be used to exactly analyze SRGs ...
متن کاملPolarimetry of thin metal transmission gratings in the resonance region and its impact on the response of metal-semiconductor-metal photodetectors
The resonance behavior of metal transmission gratings and its impact on the response of metal-semiconductor-metal ~MSM! photodetectors have been studied experimentally and theoretically. The metal gratings, with finger spacings in the subwavelength region of the visible light, were fabricated using e-beam lithography and lift-off. Strong resonances have been observed only in the S polarization....
متن کاملSubwavelength surface-relief gratings for stellar coronagraphy.
We present a new design of a phase mask coronagraph implemented with subwavelength diffractive optical elements consisting of optimized surface-relief gratings. Phase mask coronagraphy is a recent technique that seeks to accommodate both high dynamic and high angular resolution imaging of faint sources around bright astrophysical objects such as exoplanets orbiting their host stars. The origina...
متن کاملDevelopment of a large-area plasmonic sensor substrate with dielectric subwavelength gratings using nanoimprint lithography.
We demonstrated an enhanced surface plasmon resonance (SPR) detection by incorporating subwavelength SiO2 gratings built on a thin silver film. Large-area SiO2 gratings were fabricated by nanoimprint lithographic technique and dry etching processes and used to sense a surface-limited biomolecular interaction. Numerical results based on rigorous coupled-wave analysis method exhibited that the di...
