Abstract
A system and method for twisting together two fibers to create an optical fiber coupler is disclosed. In one embodiment, the two optic fibers are threaded through a chuck, which is rotated by a motor to create an amount of twist in the two optical fibers necessary to cause a light signal transmitted through the twisted fibers to have a desired polarization state. A heater applies heat to the twisted fibers while rotating the chuck to create an optical fiber coupler.
