Fiber Optic Depolarizer
The Phoenix Photonics optical fiber depolarizer is an all-fiber Lyot type device producing pseudo-random polarization output, with low degree of polarization (DOP), for any input state of polarization (SOP).
The fiber optic depolarizer is a passive device utilising the coherence properties of the source to randomise the SOP. For optimum performance the fiber depolarizers are designed to match the source spectrum and differing requirements of optical sources from broadband ASE’s to high power amplifier pump lasers.
The principle of operation is to utilise high linear birefringence fibers to create a differential time delay between two orthogonal polarization modes. In simple terms, if the delay time is greater than the coherence time of the source then the two orthogonal polarization modes no longer have any phase relationship and add in power. Providing the optical power is equally divided between the two birefringent axes at the input then the output is depolarized. (click here to view product technical briefs)
Standard Fiber Optic DepolarizersThe standard fiber depolarizer range will depolarize a light source from >0.1nm linewidth and can be spliced or connected into a SM fiber system converting any arbitrary SOP to a depolarized output. 1 |
