ABSTRACT:
A fiber optic T-coupler comprised of solid primary and branch cores adapted to transmit light therethrough. The primary core is provided with a recess cooperating with the branch core, typically arranged at a right-angle with the primary core, to define a reflective surface whose surface area forms a ratio with the cross-sectional surface area of the primary core, which ratio corresponds to that between the light deflected by the reflective means into the branch core relative to the total light entering the primary core prior to deflection.
The reflective surface may be provided within the body of either the primary core or the branch core and plural reflective surfaces may be provided for handling bi-directional transmission or reception or for separating the transmission and reception of light.
