A device for stabilising the Bragg wave length of a Bragg network (420) with respect to temperature variations, of the type with two materials (100, 200, 300) having very different thermal dilation coefficients and adapted in order to produce, during a temperature augmentation, a relaxation of an initial pretension of the network (420), is characterised in that the materials (100, 200, 300) having very different dilation coefficients are two glasses. An optical component incorporating a Bragg network and a device for stabilising the Bragg wave length of this network with respect to temperature variations is also claimed.
