Abstract

Polarization-maintaining photonic crystal fiber couplers (PM-PCFCs) are fabricated using CO₂ laser irradiation technique. We could successfully control the states of air holes in the tapered region of coupler by appropriately adjusting the laser power in the elongation process of coupler fabrication. It was demonstrated that the air hole remaining PM-PCFC exhibited polarization-splitting characteristics in which one of the polarization modes was transmitted to the straight port and the other was transmitted to the cross port. It was also shown that the air hole collapsed PM-PCFC had polarization insensitive coupling characteristics, where the polarizations of the transmitted lights at the output ports were maintained.
