摘要： The present invention relates to a set-up and a method for repeatedly sending longitudinal displacement pulses through a length of optical fibre, the set-up using an actuator arrangement for exciting longitudinal displacement pulses, or waves, in an optical fibre. The arrangement comprises a bracket, a washer element, a piezo member arranged between the bracket and the washer element, and an optical fibre that is engaged with and extending through a passage in the washer element. The piezo member is operative, responsive to an applied voltage, to displace the washer element and the fibre engaged therewith, in the longitudinal direction of the fibre, with respect to the bracket. Thereby, a longitudinal displacement pulse may be excited in the optical fibre. The actuator arrangement may also, in the set-up according to the invention, operate as a sensor for sensing longitudinal displacements in optical fibres.

摘要： A novel method based on sequential writing for fabricating of advanced fiber Bragg gratings is disclosed. As opposed to already presented sequential methods, this scheme uses a continuous wave UV laser source and allows for a very precise control and repetitively of the formation of the gratings. Furthermore, one can use high average irradiances without destroying the fiber, resulting in a dramatical shortening of fabricating times for complex gratings.

摘要： A method and an arrangement for characterizing in-fiber gratings are disclosed. According to the invention, the characteristics of a fiber grating are analyzed by reflecting light in a measurement branch of an interferometer from the grating, and subsequently interfering the reflected light with light from a reference branch of the interferometer. A first measurement value is recorded. Then, the polarization state of the light in the reference branch is switched to an orthogonal state, whereupon a second measurement value is recorded. A polarization insensitive interference value is obtained by taking the quadratic sum of the first and the second measurement values.

摘要： A novel method and apparatus for fabrication of blazed and slanted fiber Bragg gratings is disclosed. The method comprises the step of simultaneously exposing the fiber with two mutually coherent light beams so as to create an interference pattern along a longitudinal axis of the fiber, wherein each one of said beams is brought into a line focus, which coincides with the core of the fiber. Further, the plane comprising the beams is rotated to provide a second angle relative to the fiber direction, said rotation giving rise to a blazing angle of the photo-induced grating elements.

摘要： The invention relates to methods and arrangements for channel balancing of a wavelenght division multiplexed optical signal. Channel balancing according to the invention is performed by using a resonator that provides a selection region in which a selected channel has a substantially increased power density relative to channels out of resonance. The selected channel is attenuated a desired amount, i.e. a desired amount of poer is removed therefrom, by adjusting the prperties of the selection region. In a preferred embodiment, attenuation is achieved by adjusting the selection region such that destructive interference is obtained for the selected channel in a fibre carrying the multiplexed optical signal.

摘要： A method of establishing transmission of light through a chirped Bragg-reflector, a method of analysing the power spectrum of a light signal by means of a chirped Bragg-reflector, and an arrangement for analysing the power spectrum of a light signal. The Bragg-reflector reflects, in an unperturbed state, essentially all incident light within a predefined wavelength range. The methods comprise the steps of directing the light to be analysed into an input end of a light guiding structure, such as an optical fibre, which light guiding structure is provided with a Bragg-reflector, and sending an acoustic pulse along said light guiding structure, thereby effectively lowering the reflectance of the Bragg-reflector for a certain wavelength at a certain time. By monitoring the light thus transmitted through the Bragg-reflector, power spectrum analysis of the incident light is obtained.
