MÜller–Stokes Analysis of Long Period Gratings Part II: Randomly Birefringent LPGs

We present a Muller-Stokes analysis of the polarization properties of randomly birefingent long-period fiber gratings (LPGs). Using a previously derived Muller matrix, we perform simulations of the polarization behavior in photonic crystal fibers-based tapered long-period gratings with randomly varying birefringence axes. Computer simulations show good agreement with results from experiments with a broadband-amplified spontaneous emission source and a tunable laser in combination with a polarization analyzer.
