摘要
An optical communications module is provided with an optical coupling system that includes a reflective and focusing (RAF) lens and an index-matching material that together allow air gaps along the optical pathway, which are typically associated with the use of refractive optical elements used in known optical communications modules, to be eliminated. Eliminating these air gaps allows Fresnel reflection along the optical pathway to be eliminated, or at least greatly reduced. Eliminating or reducing Fresnel reflection reduces insertion loss and optical crosstalk in the optical communications module.
