    摘要： The present invention provides a fiber Bragg Grating sequential writing method with real-time optical fiber position monitoring, characterized in that the relative phase between a fiber grating and a writing interference beam at each positioning point is determined by an interferometric side-diffraction method, and writing is sequentially performed. Accuracy in fabricating a long and complex fiber grating structure can be increased by decreasing or avoiding accumulative errors caused by long-term scan of monitoring optical fiber position, or by a means for fabricating a wanted reference fiber Bragg grating with similar settings.

    摘要： The present invention provides a two-beam interference exposure system that can be simply adjusted by rotating only one mirror. By placing a half-wave plate in one of the interference arms and precisely scanning the relative fiber position, the present invention can expose true apodized fiber Bragg gratings in a single scan by simultaneously rotating the angle of the half-wave plate. By rotationally switching the fast and slow axes of the half-wave plate, the present invention can also expose n-phase-shifted fiber grating by the same system.

    摘要： The invention provides an optical amplifying system having a structure with two amplification levels to amplify received optical signals. The optical amplifying system includes a Michelson interferometer, a preamplifier, and a post amplifier. In the preamplifier and the post-amplifier, respectively have a light pumping source, a wavelength multiplexer, and an optical gain media. The Michelson interferometer includes an optical coupler and an optical grating set composed of a pair of optical gratings. The optical gratings are located different optical passes, and its central wavelength is equal to the intended wavelength. The optical grating can be formed on a piezoelectric substrate or an electrothermal substrate so that the central wavelength can be changed by applying stress or heat. The intended wavelength reflected by the Michelson interferometer can therefore be adjusted. The preamplifier and the post-amplifier are coupled together through the optical coupler of the Michelson interferometer. Furthermore, an isolator can also be coupled between the preamplifier and the Michelson interferometer so as to avoid the backward propagation noise.
