Abstract
Light-emitting optoelectronic modules operable to generate an emission characterized by reduced speckle can include a coherent light source, a diffuser, and a Fresnel element. The coherent light source is operable to generate a coherent emission, characterized by a coherence length, incident on the diffuser. The diffuser is characterized by a divergence angle. The divergence angle is the angle between a first path-length from the diffuser to a Fresnel element and a second path-length from the diffuser to the Fresnel element, wherein their difference defines a path difference. In some instances, the path difference is substantially larger than the coherence length.
