Design and Fabrication of Integrated - Optic Disk Pickup on LiBbO_3 Substrate

摘要

An integrated - optic disk pickup device has been realized on a LiNbO_3 substrate. The device is constructed by integrating an aplanatic double - convex aspherical waveguide lens (ADCAWL), a twin-grating focusing beam splitter (TGFBS) and two waveguide deflecting prisms (WDP) on a Ti: LiNbO_3 planar waveguide. The design considerations and fabrication of prototype device are Summarized.
