Characterization of Wideband All-Fiber Waveplates
… the Huang fiber as a stack of birefringent waveplates and used this model verify the theoretically predicted polarization transformation behavior and the wideband nature of the Huang fiber. We analyzed the dependence of the polarization transformation by this device on various structural …

Design and application of near infrared tunable filter for ATST and NST
… Solar Telescope (NST), the design of achromatic waveplates, the narrowband continuum observation of a Sunspot at 1.56 um using IRIM instruments, and the coronal hole observation using the Digital Vector Magnetograph (VMG) at Big Bear Solar Observatory (BBSO). A near infrared tunable filter system …

Integrated diffractive optical elements for terahertz beam shaping and polarization control /
… performance, high contrast grating (HCG) waveplates with sinusoidal surface modulation for broadband polarization manipulation, and free-standing meta-surfaces composed of subwavelength resonators engineered to exploit electromagnetic coupling and anapole resonances for enhanced …

Quantum Imaging of Biosamples
… is analogous to the one of spatially structured waveplates called q-plates, which are built to have an azimuthally dependant optic axis. This opens the door for potentially cheaper fabrication of q-plates, and possibilities of tuning the growth of the molecules for arbitrary wavefront shaping …

Metamaterial enhanced coupling
… functioning metamaterial based terahertz waveplates that are highly efficient at a previously unachieved sub wavelength size.

A near-infrared filter system and study of solar umbral dots at 1.6 µm
… including the four pairs of calcite and the half waveplates have been tested. The results show that the optical components satisfy the specifications of the filter system. The basic theory of a Fabry-Perot filter is presented and the test procedures of the nearIR Fabry-Perot filter, ET70FS-104, …

Dynamic Plasmonic Metasurfaces in the Visible Spectrum
… optical components, including lenses, waveplates and holograms containing sub-wavelength pixels have been demonstrated in the visible wavelength spectrum. The metasurfaces are able to mould optical wavefronts into arbitrary shapes with sub-wavelength resolution by introducing spatial …
