摘要

光纤布拉格光栅(FBG)的设计通常从确定反射时所需的光谱传递函数开始。在大量的应用中,只定义了该传递函数的幅值响应。然而,为了设计任何器件,都需要大小和相位。在本文中,提出了众所周知的最小相位重建方法来确定与期望的幅度响应相关的相位响应,以便定义强加于fbg合成工具的规范。该程序使合成的光纤光栅器件具有最小可能的长度,以实现目标的光谱幅度响应。

Minimum-phase reconstruction method for the determination of the specifications of FBGs
The fiber Bragg grating (FBG) design usually starts from the specification of the required spectral transfer function upon reflection. In a large number of applications, only the magnitude response of this transfer function is defined. However, in order to design any device, both the magnitude and the phase are required. In this paper, the well-known method of minimum-phase reconstruction is proposed to determine the phase response associated to a desired magnitude response, in order to define the specifications imposed over the synthesis tools of FBGs. This procedure enables the synthesis of a FBG device with the minimum possible length to achieve the target spectral magnitude response.
