Abstract

In conventional single mode fiber, Self Phase Modulation (SPM) and Degenerate Cross Phase Modulation (DXPM) are the main non linear effects contributing to continuum generation. By controlling the polarization state of the light pumping the fiber and by selecting the polarization state out of the fiber, the spectrum of continuum generation can be optimized for optical coherence tomography (OCT). We investigate the effects of polarization control and selection on continuum light source consisting of a femotosecond Nd:glass laser and ultra high numerical aperture (UHNA) single mode fiber. The point Spread Function (PSF) can be improved by controlling linear input polarization or by selecting one of two orthogonal polarization modes at the output.
