Precise method for angular alignment of birefringent fibers based on an interferometric technique with a broadband source.

Abstract: A new method for precisely aligning the principal axes between two birefringent fibers is presented using a Michelson interferometer and a broadband source Angular alignment can be accomplished by measuring the interference peak value corresponding to the rotation angle between the principal axes of the birefringent fibers Angular alignment accuracy is limited by the mode coupling produced near the connection with reduced dependence on the fiber crosstalk Following the experiment, minimum angular misalignment was +/-0086 degrees , which corresponds to -56-dB crosstalk at the connection

On wave-breaking free fiber lasers mode-locked with two saturable absorber mechanisms

Abstract: We propose a hybrid mode-locking scheme for wave-breaking free fiber lasers based on a saturable Bragg reflector and the nonlinear polarization evolution in the fiber section. With this scheme, the self-starting operation is ensured by the saturable Bragg reflector while the nonlinear polarization evolution acts as an additional pulse shaper in the steady state. Owing to the sensitivity of the pulse dynamics to filtering effects, a tuning range of more than 10nm as well as the suppression of undesired modes of operation became possible. The impact of the modulation depth and the non-saturated losses is discussed via comparative measurements with different saturable Bragg reflectors.

Generalized Mueller matrix method for polarization mode dispersion measurement in a system with polarization-dependent loss or gain.

Abstract: A generalized Mueller matrix method (GMMM) is proposed to measure the polarization mode dispersion (PMD) in an optical fiber system with polarization-dependent loss or gain (PDL/G). This algorithm is based on the polar decomposition of a 4X4 matrix which corresponds to a Lorentz transformation. Compared to the generalized Poincare sphere method, the GMMM can measure PMD accurately with a relatively larger frequency step, and the obtained PMD data has very low noise level.

Influence of temperature on birefringence and polarization mode dispersion in photonic crystal holey fibers

Abstract: Summary form only given. Applying a fully vectorial method, we calculated the dependence of modal birefringence and polarization mode dispersion upon wavelength in photonic crystal holey fibers of different structure. We also determined the sensitivities of these two parameters to temperature. Our results show that in the analyzed spectral range modal birefringence increases while polarization mode dispersion decreases with wavelength in both structures. The sensitivity of modal birefringence to temperature is positive and increases with wavelength while the sensitivity of polarization mode dispersion is negative and decreases with wavelength. The spectral behavior of both sensitivities is opposite to that observed in classical elliptical-core fibers.
