  • Inducing or enhancing electro-optic properties in optically transmissive material with simultaneous UV irradiation and electric field application
    Patent number: 5966233
    Abstract: A method of inducing or enhancing the electro-optic properties of an optically transmissive material such as an optical fiber (1) which comprises applying an electric field by means of electrodes (4) to the optical fiber and subjecting the material to UV radiation (9).

  • Optical grating
    Patent number: 5830622
    Abstract: An optical grating is formed by exposing linearly spaced regions of an optical fibre (10), typically a germanosilicate core fibre, to UV irradiation to produce spaced apart regions (12 and 13) of differing refractive index within the core (11) of the fibre. The grating characteristics are modified to create a relatively complex structure, for example a pi- shifted distributed phase structure, by post-processing the grating. This is achieved by exposing at least one concomitant region (14) of the grating to localised UV irradiation.
