Abstract
Stimulated Brillouin scattering (SBS) is effective for realizing a laser with an
ultra-narrow linewidth. Although photonic crystal fiber (PCF) is
considered an excellent medium to achieve
SBS, it does not meet the
requirements of low loss, large birefringence, and ease of
fabrication. We propose a
polarization-maintaining PCF (PM-PCF) structure and theoretically
analyze the effects of the geometric structural parameters of the
PM-PCF on various optical properties. Our theoretical analysis and
experimental results contribute to the advancement of the field of
ultra-narrow linewidth fiber lasers, distributed fiber sensing, and
fiber-optic gyroscopes related to SBS.
