研究了在芯间距为40 μm的六边形多芯掺铒光纤中平行制备7个光纤分布式反馈激光器的方法。采用单次UV铭文曝光制备了长8 cm、工作波长在1545 nm附近的DFB光栅腔。我们观察到每个激光的双偏振,单纵向模式工作,线宽低于300 kHz。
We demonstrate parallel fabrication of seven fiber distributed feedback (DFB) lasers in a hexagonally arrayed multicore core Er doped fiber with 40 μm core spacing. DFB grating cavities 8 cm long and operating near 1545 nm were fabricated with a single UV inscription exposure. We observed dual polarization, single longitudinal mode operation with a linewidth below 300 kHz for each laser.
