| 英文摘要 | 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. |
