Abstract:
An optical fiber collimator in an optical system, comprising:a pair of optical fibers having cleaved planes to provide a substantially uniform angled side surface for forming a prescribed angle relative to the optical axis of the optical system, the pair of optical fibers disposed coplanarly in the object plane of the optical system for sharing the optical axis and separated from each other and from the optical axis on the same object plane; and a microlens having a sloped rear surface opposite a rotationally symmetric microlens surface which bound a volume having a homogeneous index of refraction, the microlens optically coupled to the pair of fibers positioned near the focal plane containing the optical axis of the microlens for the generation or reception of collimated beams at the prescribed angle relative to the optical axis of the microlens, wherein the microlens has a single refractive surface.
