Abstract
An optical coupler for coupling light between a light emitter and an optical fiber includes a substrate for maintaining a bend in an optical fiber through which light can be coupled between an optical fiber core and the light emitter. The substrate includes a cavity which extends in a direction substantially perpendicular to a plane defined by the fiber bend so as to enable the light emitter to be secured to the substrate to minimize a propagation distance of light to be coupled through the substrate. The light emitter includes first and second substantially spherical lenses, one of which being disposed in the cavity so as to increase optical coupling efficiencies and result in a compact coupler design.
