摘要
A fused optical coupler comprising a polarization maintaining fiber and a standard fiber is provided. The cross-section of the said standard fiber is smaller than the cross-section of the polarization maintaining fiber in the area of fusion of the coupler. The internal forces in the coupling area are sufficiently low to provide an extinction ratio of more than 20 dB at the output of the polarization maintaining fiber.
