Abstract: This paper hag probed into a new type of waveguide lenses which may be called the waveguide eleotrooptio Bragg grating lens. According to the eleotrooptio effect of eleotrooptio-crystal and the principle of diffraction of Bragg grating, the refractive index change can be induced in the waveguide under an aluminum electric pole when a suitable do voltage is applied to it and the chirped grating with inclined stripes is formed. The pole is a chirped interdigital one with inclined stripes made with conventional lithographical technique. The grating diffracts and focuses the incident light beam and acts as a lens. This type of lenses has the advantages of being simple in manufacturing and easy in integrating with other components of integrated optics. Our grating has a 40mm focal length and 14μm diameter focal spot.
