Abstract
A method and apparatus for controlling propagation of a light beam using a beveled endcap of an optical fiber, where the endcap has a first end coupled to the optical fiber and a second end having a bevel that circumscribes a facet. The bevel has an angle relative to the plane of the facet that directs a peripheral portion of the light beam towards a lens and the facet directs a central portion of the light beam towards the lens. As such, the light beam is collimated with substantially all of the power of the light beam propagating through the lens and all the power delivered with fiber core to the output endcap is propagating through the lens despite the divergence of the delivered beam and a restricted aperture of the lens.
