Etched and fused hemispherical microlenses for coupling single-mode laser into single-mode fiber |
| |
| Abstract: | The contour lines of the coupling efficiency of hemispherical mierolenses determined by parameters of single-mode laser and single-mode fiber are calculated. The method for etched and fused fabrication on the single-mode fiber end is described. Experimental results for hemispherical lenses are in good agreement with the theory, and 70% of the optimum theoretical value has been obtained. |
