We demonstrate electrical tunability of a fiber laser using a liquid crystal photonic bandgap fiber. Tuning of the laser is achieved by combining the wavelength filtering effect of a tunable liquid crystal photonic bandgap fiber device with an ytterbium-doped photonic crystal fiber. We fabricate an all-spliced laser cavity based on the liquid crystal photonic bandgap fiber mounted on a silicon assembly, a pump/signal combiner with single-mode signal feed-through and an ytterbium-doped photonic crystal fiber. The laser cavity produces a single-mode output and is tuned in the range 1040-1065 nm by applying an electric field to the silicon assembly.
我们展示了一种使用液晶光子带隙光纤的光纤激光器的电可调性。通过将可调谐液晶光子带隙光纤器件的波长滤波效应与掺镱光子晶体光纤相结合来实现激光器的调谐。我们基于安装在硅组件上的液晶光子带隙光纤、具有单模信号直通的泵浦/信号合束器以及掺镱光子晶体光纤制造了一个全熔接激光腔。该激光腔产生单模输出，并通过向硅组件施加电场在1040 - 1065纳米范围内进行调谐。
