High-extinction-ratio resonant cavity polarizer for quantum-optics measurements.
The use of a high-finesse Fabry-Perot ring cavity with an odd number of reflections as a high-extinction-ratio resonant polarizer is shown. Experimental results from quantum-noise measurements using resonant cavities as spatial and spectral filters and precision polarizers are presented.
متن کاملWide-angle near infrared polarizer with extremely high extinction ratio.
An infrared polarizer is designed with a predicted extremely high extinction ratio exceeding 3 × 10(16) and transmittance higher than 89% for one polarization in the wavelength region from 1.6 to 2.3 µm. Moreover, the performance does not start to deteriorate until 60° tilting angle. The wide-angle high transmission is attributed to the excitation of magnetic polaritons and suitable LC circuit ...
متن کاملFlexible terahertz wire grid polarizer with high extinction ratio and low loss.
An aluminum-based terahertz (THz) wire grid polarizer is theoretically investigated and experimentally demonstrated on a subwavelength thin flexible and conformal foil of the cyclo-olefin Zeonor polymer. THz time-domain spectroscopy characterization, performed on both flat and curved configurations, reveals a high extinction ratio between 40 and 45 dB in the 0.3-1 THz range and in excess of 30 ...
متن کاملAsymmetric plasmonic-dielectric coupler with short coupling length, high extinction ratio, and low insertion loss.
Asymmetric directional coupling between a hybrid plasmonic waveguide with subwavelength field confinement and a conventional dielectric waveguide is investigated. The proposed hybrid coupler features short coupling length, high coupling efficiency, high extinction ratio, and low insertion loss; it can also be integrated into a silicon-based platform. This coupler can be potentially adopted for ...
متن کاملFabrication of integrated Ti:LiNbO3 waveguide polarizer
The design and fabrication of an integrated waveguide polarizer in z-cut LiNbO3 crystals are reported. Singlepolarization guiding is achieved by careful selection of Ti diffusion parameters exploiting the transverse electric/ transverse magnetic TE/TM refractive index anisotropy. Fabricated Ti:LiNbO3 waveguide polarizers of 1.5 cm length exhibit less than 0.2-dB/cm propagation loss at TM and 33...
