A study has been conducted in the areas of polarization modulation and splicing techniques for a polarization maintaining PANDA type fiber. Polarization modulation was achieved by compressing the fiber both along the fast and slow axes. A sensitivity of 16.69 rad/(g/um) and 27.56 rad/(g/um), corresponding to a maximum phase diffrerence of 2.39 radians and 3.96 radians for compressing along the x and y birefringent axis, respectively, was achieved, with the compression material complying to a 15 degree arc around the fiber circumference. Polarization cross coupling was measured to be 0.6% for compressing with a force of 1.3 g/um. Polarization cross coupling curves were derived in terms of error in angle of applied force and polarization mode coupling alignment at the fiber input. Finite element analysis was successfully used to predict the birefringence change of the polarization modulator. Also presented are methods to improve the fiber end face perpendicularity in preparation for splicing. Two methods are proposed for detennining fiber end inclination angle with accuracy of 0.03 and 0.09 degrees. Fiber ends were prepared with inclination angles less 0.3 degrees.
