ABSTRACT:
A compact optical coupling device particularly adapted for coupling between a source and two optical fiber ends having a function of separation of the radiation from the source between these two ends. The device comprises a small-size separator cube, a plano-convex microlens whose flat face is bonded to the input face of the separator cube, and two square-section end-pieces bonded to the two output faces of the separator cube, each enclosing one fiber end.
