| Abstract: | Through analyzing the different typical coupling properties of semiconductor laser to optical fiber,the structures of lensed fiber is presented ,to enhance the coupling efficiency largely. The principles and processes to fabricate lensed fibers, such as fused-drawn taper, chemical etched taper, grinding and polishing,micromachining,GRIN fiber lens and molding lens, and the characteristics of these lensed fibers are introduced. Furthermore,these lensed fibers are appreciated. A new scheme to enhance the coupling efficiency and alignment tolerance and reduce the insert loss for LD and fiber is reported. |
