The coupling and alignment tolerance are optimized based on a theoretical analysis for the coupling between a highly elliptical laser diode and a single-mode fiber with a wedge-shaped end face. The optimized design parameters including the working distance, wedged angle are obtained for various aspect ratios of the laser diode. It is demonstrated that the coupling efficiency is a strong function of...
Automation of fiber-to-optic alignment is critical to the development of cost effective fiber-optic component manufacturing technologies. Key to the alignment automation is the angular alignment automation, which is now unavailable. But angular misalignments are unavoidable in practical fiber-optic aligning process. This work evaluates the effects of pitch, yaw, and roll angular misalignments for...
