Paper Abstract

In this work, we proposed a dual-core fiber coupler. Identical long-period fiber grating is written in each core of the dual-core fiber by using point-by-point high-frequency CO2 laser irradiation. The peak attenuations of the two similar LPGs are -19.8 dB and 13.2 dB, respectively. And the proposed coupler can achieve a peak coupling efficiency of 48%.
