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.
Claims29
An apparatus, comprising:
- a first chuck to hold a first optical fiber and a second optical fiber;
- and
- a first motor coupled to rotate the first chuck in relation to the holder to create an amount of twist in the first and second optical fiber necessary to cause a light signal transmitted through the twisted fibers to have a desired waveform,
- wherein the first and second optical fibers are wrapped around a spool disposed on the first chuck.

A method, comprising:
- threading a first optic fiber and a second optic fiber into a first chuck;
- sending a light signal to test polarization states present in the first and second optic fiber;
- and
- using a first motor to rotate the first chuck to twist the first and second fiber to achieve a desired wave form,
- wherein the first and second optic fibers are wrapped around a spool disposed in the first chuck.
