Abstract
An optical fiber collimator ( ) in an optical system, includes a pair of optical fibers ( ) having emitting 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 ( ) are 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. Optically coupled to the pair of fibers, a microlens ( ) has a sloped rear surface ( ) opposite a rotationally symmetric microlens surface ( ) which bound a volume having a homogeneous index of refraction. The pair of fibers ( ) are 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 ( ).
