Abstract
A bidirectional stress tuner of optical fibre raster for tuning peak wavelength of optical fibre raster is composed of the first and the second horizontal arms for fixing the optical fibres at both end of raster to them, and guide track with normal triangular internal cavity for containing said raster in it. Said two horizontal arms are electromagnetically coupled to drive mechanism to move closeto or far from each other, so compressing or stretching the raster. Its advantages include uniform stress, no deformation, no increasement of reflection bandwidth, and better turning renaturation.
