Brief

The article proposes and demonstrates a compact, all-fiber polarization beam splitter (PBS) fabricated using a simple method based on coupled microfibers, and successfully applies it for passively mode-locking fiber lasers at 1.0 μm and 1.5 μm wavelength bands with performance comparable to systems using bulky PBSs.

Summary

This paper introduces an all-fiber polarization beam splitter (PBS) constructed from two parallel coupled microfibers. The authors note that commonly used PBSs are bulky and not truly all-fiber, and previous special-fiber-based PBSs require complex fabrication. The proposed microfiber-based PBS offers advantages such as simple fabrication, compact size, and variable polarization extinction ratio (PER) and operation bandwidth.
