High-power fiber laser with a polarizing diffraction grating milled on the facet of an optical fiber
We milled a sub-wavelength diffraction grating on the facet of a large mode area fiber. The diffraction grating had different reflectivities for TE and TM to the laser with a perpendicularly cleav...

Extraordinary transmission through dielectric screens with 1D sub-wavelength metallic inclusions
Extraordinary optical transmission (EOT) through dielectric screens periodically loaded with sub-wavelength 1D discontinuities, such as apertures or metallic insets is analyzed. The results of the analysis and computational electrom...

Anti-reflection and polarizing photonic structures for high-power fiber applications
We investigated behaviours of 1D binary diffraction gratings fabricated on optical fiber facets. Only sub wavelength structures were considered to suppress higher diffraction orders. The aperiodic rigorous...

Effective spectral optical functions of lamellar nanogratings
Spectral properties of lamellar sub-wavelength gratings (nanogratings) are described by effective medium approximation (EMA). Analytical spectral formulae dichroism for absorbing ones is discussed for model cases and gr...

Monitoring of overmodulation effect in high efficient transmission gratings produced in photopolymers
In our laboratory, we deal with characterization of diffraction gratings produced in photopolymers. In such recording systems, the diffraction of light is induced via spatial modulation of refractive index and the diffr...
