Abstract
A two-part optical coupling subassembly includes a main lens formed with a cavity, the main lens including two surfaces formed in the cavity and oppositely inclined at an off-vertical angle from a central vertical plane of the cavity such that the two surfaces are symmetric with respect to the central vertical plane; a beam router embedded in the cavity, the beam router including first and second beam router surfaces lying on the two surfaces of the main lens respectively, and a partially reflective coating on at least one of the beam router surfaces; and a transparent adhesive provided between the two lens surfaces and the first and second beam router surfaces.
