<p>An optical waveguide is formed in a body of crystalline material and consists of a device having a pair of contiguous regions (1, 2) one of which has a lower refractive index than that of the other. The lower refractive index results from damage to the lattice structure of the crystalline structure of the material of the respective region caused by bombardment of the crystalline lattice with energetic ions.</p> |
