摘要： The present invention relates to an optical component, which comprises an optical fibre, which has a minimal functional arc radius in each point thereof, and which includes a thermally compensated portion, and a Bragg grating provided in a region of the thermally compensated portion. The optical fibre component comprises furthermore a temperature-compensating structure, which holds the thermally compensated portion of the optical fibre under tension in a linear direction for athermalizing the Bragg grating, and a housing for mechanical protection of the Bragg grating, which is provided with at least a first lead-through, and which housing has a maximal extension in the linear direction from a first housing end to a second housing end. The first lead-through has an exit end located outside the housing and an entrance end located inside the housing. The optical fibre furthermore includes at least a first connecting portion, which extends from a first end of the thermally compensated portion to and through the first lead-through, and at least a first exit portion which extends from a lead-through exit end of the first connecting portion. The first lead-through is located and arranged such that the first exit portion is bendable to the minimal functional arc radius without protruding more than half the minimal functional arc radius in the linear direction beyond the first housing, also when a shorter exit portion is extended to a length equal to the circumference of a circle with the minimal functional arc radius.

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 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： Improvements relating to thermally tunable fiber optical devices have been disclosed. In one aspect, a thermally tunable fiber Bragg grating device is provided with one or more heaters to (3a, 3b) produce a desired temperature profile along the grating, and one or more supporting auxiliary heaters (5a, 5b) are provided at the edges of the grating in order to compensate for temperature drops caused by heat loss to lower temperature surroundings. In another aspect, two heating structures are thermally connected to each other, such that dissipated heat from one of the structures supports the heating effect of the other structure.
