ABSTRACT:
An apparatus for aligning monomode optical fibers utilizes a first optical coupler for injecting light into a straight section of a first fiber through its buffer, a first pin for bending the first fiber downstream of the first optical coupler to convert cladding modes into core modes, a second pin for converting core modes into cladding modes in a second optical fiber, a second optical coupler for withdrawing light from the second optical fiber through its buffer, and feedback control to optimize the amount of light transferred from the first fiber core to the second fiber core.
