文摘A non-adiabatic microfiber coupler is fabricated by flame brushing technique and then theoretically and experimentally analyzed.The effective length of the microfiber coupler is determined by simulation,and a low-noise laser is demonstrated using various lengths of erbium-doped fiber(EDF) when incorporated in a laser setup.At 18.6-mW input pump power,the maximum output power of 20 μW and the lowest lasing threshold of 3.8 mW are obtained with a 90-cm-long EDF.
