“…The plasma treatment DEs condensed the surface roughness. Since the surface roughness of the film has same variation tendency as that of original substrate [19]. Absolutely, the roughness condensed with plasma treatment up to some maximum value and then again induces with further increasing (i.e.…”

“…The resonant wavelength of such DEs can be easily adjusted for reflectors, polarizers, band-pass and band-stop, by changing the structural and material properties. As a consequence of their frequent usage in parametric spaces, variety of new models are being developed [17][18][19][20]. In such models, GMR color DEs in reflection or transmission domain receives great attention [21,22].…”

In this research work, two polydimethylsiloxane diffractive elements (DEs) of 3 mm thickness under the same conditions are fabricated using molding technique and one DEs rough surface is modified by plasma O 2 treatment in a vacuum chamber. The effects of both rough surface DEs on the structure and optical properties are investigated by atomic force microscope, white light interferometer and FDTD simulated, which indicates that the plasma O 2 treatment induces the formation of nanostructures and decreases the surface roughness up to some roughness level. The optical transmittance, reflectance, absorption, Raman scattering spectra and optical coefficient measurement provides better results to polymer DEs, to be used as replica, efficient and cost effective. Furthermore, the stretchable technology is applied on both DEs, which provides results towards diffraction grating and thus, have widespread applications in optical transmission and reflection domain such as measuring, imaging, coding and solar energy.

“…As polarisation insensitivity is the nature of 2D GMRFs due to their symmetry profiles, studies on 2D GMRFs have attracted increasing attention in both theory [14,15] and experiment [16][17][18][19][20][21]. In 2007, Fehrembach et al [16] demonstrated the feasibility of 2D doubly periodic gratings and their interest for unpolarised narrowband filtering by obtaining experimentally a 0.5 nm bandpass polarisation-independent reflection filter at telecom wavelength (1520-1570 nm), with a transmittivity minimum of 18%, under normal incidence, with a standard collimated beam.…”

Two-dimensional (2D) non-polarising transmission filters based on guided-mode resonance (GMR) for the optical communication wavelength O-band and C-band have been designed and fabricated. This type of GMR filter (GMRF) is composed of a 2D metal grating layer, a waveguide layer, and a glass substrate. The rigorous coupled-wave analysis is used to calculate the transmission spectra of the designed GMRFs. The grating structures of the GMRFs are patterned by electron beam lithography. The transmission spectra of the fabricated GMRF samples at different incident angles are measured by rotating a motorised stage and the experimental results agree closely with the theoretical designs. The measured results show that the transmission spectra of the two GMRF samples are insensitive to the incident angle. A deviation of 1°in the angle of incidence from normal illumination does not lead to the reduction of the peak transmittance. Although a narrow secondary resonance appears at oblique incidence for transverse-magnetic polarisation, the resonance spectral shapes for transverse-electric polarisation and TM polarisation are nearly identical at incident angles of 0-1.5°. Compared to previous reported non-polarising GMRFs, the angular tolerances of the fabricated samples are remarkably enhanced.

“…Therefore, polarization‐insensitive properties of GMRFs are required. Although polarization‐insensitivity is the nature of two‐dimensional (2D) GMRFs due to their symmetry profiles, there is a strong angular dependence of the resonance wavelength on the incident angle. For a 2D GMRF, slightly offnormal illumination leads to two narrow sidebands and a spectral shift.…”

“…For a 2D GMRF, slightly offnormal illumination leads to two narrow sidebands and a spectral shift. Moreover, due to the difficult control of grating depths of the 2D GMRFs, the measured nonpolarizing spectra are not satisfactory. Thus, low‐cost polarization‐independent 1D GMRFs are obviously more desirable.…”

Mounting‐insensitive nonpolarizing guided‐mode resonance filters (GMRFs) for the optical communication wavelength O‐band and C‐band have been designed and fabricated. The rigorous coupled‐wave analysis (RCWA) is used to calculate the reflection spectra of the designed GMRFs. The grating structures of the GMRFs are patterned by interference lithography with two ultraviolet laser beams. The reflection spectra of the fabricated samples at different incident angles are measured by rotating a motorized stage. Compared with previous reported one‐dimensional nonpolarizing GMRFs, the tolerances of conical angle of the fabricated samples are remarkably improved.
