Paper Abstract
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 coupled wave analysis, the Fourier modal method and the finite-difference time-domain numerical methods were used to compute and optimize the modal reflectance of the investigated structures. Optimized gratings were milled on fiber facets by focused ion beam. One of the gratings was tested in a thulium-doped fiber laser where it acted as a low re ectivity polarizing output mirror. A slope efficiency of the laser and a beam quality parameter were conserved while lasing threshold slightly increased.
