An all-fiber, all-states of polarization linear design depolarizer is provided. It is made of two polarization combiners (PC,PC) with a 2&#xd7;2 directional coupler (DC) between them. The connections between the coupler (DC) and the two polarization combiners (PC,PC) have optical phase delays (L,L) and half wave polarization rotators (PR,PR,PR) to make proper adjustments.

All-fiber linear design depolarizer for all-states of polarization

An all-fiber depolarizer having a linear design includes a directional coupler associated with a polarization combiner. Linear light is pumped into the coupler where its intensity is split in two. Between the coupler and the combiner there is included an optical delay and the polarization of one intensity is made orthogonal to the other, as they enter the polarization combiner. The combiner combines the orthogonal polarizations and the light exits by an output in a depolarized state.
