摘要	An optical apparatus includes an optical fiber (13). A plurality of individual optical fiber deformation structures, comprising e.g. acoustic wave propagation members (18) and acoustic wave generators (24), are positioned adjacent along a length of the optical fiber. Each of an individual optical fiber deformation structure introduces a mechanical or index deformation of a portion of the optical fiber (36) (e.g. by a flexural acoustic wave) to create perturbations in the optical modes in the fiber and provide a coherent coupling between two modes in the optical fiber. This apparatus provides a wavelength tunable bandpass filter (e.g. acousto-optic tunable filter, AOTF) and can be used to recover the gain flatness of erbiumdoped fiber amplifiers (EDFA) or as add/drop filter.
其他摘要	光学设备包括光纤（13）。多个单独的光纤变形结构，包括例如声波传播构件（18）和声波发生器（24）沿光纤的长度相邻定位。每个单独的光纤变形结构引入光纤（36）的一部分的机械或折射率变形（例如通过弯曲声波）以在光纤中的光学模式中产生扰动并提供两种模式之间的相干耦合。在光纤中。该装置提供波长可调带通滤波器（例如声光可调谐滤波器，AOTF），并可用于恢复掺铒光纤放大器（EDFA）的增益平坦度或作为分插滤波器。
