A new scheme of aspherical microlense for efficient

We propose and demonstrate a new scheme of aspherical microlens (ASM) employing a singlestep grinding technique with fully automated process for efficient coupling between the highpower 980nm laser diodes and single mode fibers. The grinded fiber endface exhibited a doublevariable curvature in the major axis, and was clearly observed for both major and minor axes after slight fusion polish.

However, no matter how close one places such fiber waveguides to such a collimating lens, off axis rays may still fall outside the acceptance angle of the fiber waveguides. Moreover, cylindrical fiber lenses with round or other conic crosssections may correct well onaxis but quickly degrade offaxis. This affects coupling efficiency adversely.
