Lithium niobate fibers and waveguides: fabrications and applications

In this paper, we shall briefly present some recent works done on lithium niobate fibers and waveguides. There are two major parts. The first part introduces the fabrication techniques for LiNbO/sub 3/ fibers and waveguides, which include the growth of lithium niobate fibers by laser-heated pedestal growth method and the fabrication of high aspect ratio submicron lithium niobate waveguide by focused ion beam lithography. The second part focuses on the application of lithium niobate fibers and waveguides, which include holographic storage in lithium niobate fibers, fast speed wavelength tunable filter, subpicosecond true time delay line, and low crosstalk microchannel plate spatial light modulator. Finally, a brief summary is provided.
