Abstract
A method and apparatus of coupling pump light from an extended source to an optical waveguide is disclosed. The coupling is preferably achieved through the use of a v-groove in the optical waveguide and an angle-selective mechanism that enables the angular distributions of the pump light to be optimized for optimal coupling via facets of the v-groove. Embodiments of the apparatus use a wedge, a double wedge, mirrors, or composite lenses to affect the angle selection of the pump light.
