Abstract
本发明公开的用于光纤拉曼放大器增益平坦的啁啾布拉格光纤光栅滤波器,包括一段紫外光写入的光纤布拉格啁啾光栅,光纤布拉格啁啾光栅的一端连接FC/APC接头,另一端连接FC/PC接头。该啁啾布拉格光纤光栅滤波器结构简单,通过选择不同的光纤光栅长度,啁啾系数以及光栅每个部位的紫外光写入能量不同,可以灵活调节损耗光谱,使其和光纤拉曼放大器实现宽带增益平坦化所需要损耗的光谱取得很好的一致,达到良好的光纤拉曼放大器增益平坦化效果,本发明适用于光纤拉曼放大器。
The chirped fiber Bragg grating filter used for fiber Raman amplifier gain flatness disclosed by the present invention includes a section of fiber Bragg chirped grating written by ultraviolet light, one end of the fiber Bragg chirped grating is connected to the FC/APC connector, and the other end is connected to FC/PC connector. The chirped fiber Bragg grating filter has a simple structure. By choosing different fiber grating lengths, chirp coefficients, and different ultraviolet light writing energies at each part of the grating, the loss spectrum can be flexibly adjusted to achieve broadband with fiber Raman amplifiers. The spectrum of the loss required for gain flattening is well consistent, and a good gain flattening effect of the optical fiber Raman amplifier is achieved. The invention is suitable for the optical fiber Raman amplifier.
