MICROLENS ARRAYS
SPHERICAL AND ASPHERICAL MICROLENS ARRAYS Major appliions for lens arrays with spherical or aspherical curvature are imaging and illumination as well as the effective collimation of laser light. Lens apertures from mm up to mm are possible. High filling factors and minimum dead zones allow unique beam shaping results.
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.
Design and fabriion of a biconvex aspherical microlens ...
This paper introduces a biconvex microlens to maximize the light coupling between an edge emitting laser diode (LD) and an optical fiber. Both convex surfaces have different profiles along their x and yaxis so that the elliptical light beam from an LD can be fed into the core of a fiber.

Microlenses, explained by RP Photonics Encyclopedia ...
Microlenses can be based on different operation principles: Some of them simply work as refractive lenses, just as traditional large lenses. A radially varying change of optical phase, which is the essential function of a lens, is obtained from a radially varying thickness of the device.; In order to keep the thickness very low despite a substantial dioptric power, one can use the shape of a ...
