“…They are an attractive alternative to conventional polarizers, since they are compact and planar and they have high performance providing high extinction ratios and transmittance and reflectance over a wide incident angle and wavelength range. Moreover, metal wire gratings are compatible with integrated circuit fabrication which facilitates the use of optical components such as polarizers, beam splitters, isolators, and wave plates in nanophotonic, fiber optic, display and detector devices [9][10][11][12][13].…”

We have fabricated, characterized and theoretically analyzed the performance of bilayer (or stacked) metallic wire-grids. The samples with 100 nm period were fabricated with extreme-ultraviolet interference lithography. Transmission efficiency over 50% and extinction ratios higher than 40 dB were measured in the visible range with these devices. Simulations using a finite-difference time-domain algorithm are in agreement with the experimental results and show that the transmission spectra are governed by Fabry-Perot interference and nearfield coupling between the two layers of the structure. The simple fabrication method involves only a single lithographic step without any etching and guarantees precise alignment and separation of the two wire-grids with respect to each other.

“…While various wire-grid polarizers operating in UV to infrared wavelengths were studied previously [25][26][27][28][29][30][31][32][5][6][7][8], high-performance broadband visible polarizers covering from ~ 400 nm to ~ 700 nm were not reported. Our broadband visible polarizer is based on a nanowiregrid design.…”

“…In addition to low-cost and high performance, one key advantage of a nanostructure-based optical device is its monolithic integration capability. Previously [6], we reported an integrated optical isolator based on fabricating a thin nanowiregrid polarizer monolithically onto a Faraday magneto-optic garnet substrate.…”

Nano-optic retarders and polarizers based on dielectric and metal nano-gratings were fabricated by UV-nanoimprint lithography. Different from conventional nanostructure-based optical devices, atomic layer deposition, a highly uniform and conformal deposition process, were utilized to fill trenches of the both dielectric and metal nano-gratings. The resulted immersion nano-grating design opens a path for innovative nano-grating based optical devices and integrated optical devices. As an example, a high-performance fully-buried aluminum nanowire-gird polarizer was developed which allowed us to achieve a monolithically integrated visible circular polarizer. The ability to integrate multiple nanostructure-based optical layers opens a path for innovative integrated optical devices as well as a new strategy for driving both miniature and cost.
