A method for recovering an initial linear state of polarization, of an optical beam after the beam has passed through an optical fiber and whose polarization state was disrupted, attaining power which is directly proportional to the power of the beam before it has passed through the optical fiber. The method comprises: splitting the beam into two beams, a first beam with a first polarization state and a second beam with a second polarization state, the second polarization state being orthogonal to the first polarization state; changing the polarization state of the first beam; and combining the first and second beams in half of their intensities into at least one linearly polarized beam. This way a linearly polarized output beam with power that is directly proportional to the power of the beam prior to its passing through the optical fiber is achieved.

System for recovering input polarization state of optical beam at proportional intensity

A fibre optic coupler assembly for optically aligning a sectioned fibre optic cable, the cable having a first end and a second end and comprising one or more fibre optic cores. The assembly comprises a first holder for holding the first end; a second holder for holding the second end coupled to the first end; a retractor for retracting the second end; an aligning unit comprising a resilient construction having a conduit passing through it, for linear alignment of the ends; whereby the first and second ends are coupled by the respective holders and whereby the second end can be linearly aligned in the conduit of the aligning unit, retracted using the retractor, and rotated to obtain rotational alignment of the fiber cores of the ends.
