Abstract
An optical coupler can be provided for coupling a light beam into a waveguide. The optical coupler can include a stepped structure, such as to reduce difficulties during manufacture, reduce expenses associated with manufacture, and additionally, to provide an increased acceptance angle of the optical coupler. The waveguide can include a guiding region where a cladding thickness can be increased relative to a coupling region, such as to reduce losses due to evanescent outcoupling in the guiding region.
