研究了熔融拉锥光纤型波分复用器制备过程中各相关参量对其最小信道间隔的影响。并根据理论模拟的结论设计了新型的熔融拉锥装置,其中加热装置为有较长均匀加热区域的条形加热炉,使熔融拉锥光纤型波分复用器的耦合长度显著加长,改善了传统拉锥方法对这一类型波分复用器可达到的最小信道间隔的限制,得到了初步实验结果,最小信道间隔达到3.01 nm。 The influence of the relevant parameters on the minimum channel spacing during the preparation of fused taper fiber type WDM was studied. According to the theoretical simulation results, a new type of taper tapping device is designed, in which the heating device is a strip-shaped heating furnace with a long uniform heating area, which significantly increases the coupling length of the taper fiber type WDM, The traditional coning method limits the minimum achievable channel spacing for this type of wavelength division multiplexer. Preliminary experimental results have been obtained with a minimum channel spacing of 3.01 nm.
