    YBa2Cu3O7-δ (YBCO) with low RF losses has been successfully deposited onto lithium niobate (LNO) to improve the performance of electrooptic Mach-Zender modulators. Epitaxial, c-axis oriented superconducting YBCO thin films ...
  • Reduced microwave losses YBa[sub 2]Cu[sub 3]O[sub 7 - delta] thin films on electro-optic LiNbO[sub 3] crystals

    We report on the growth of epitaxial YBa2Cu3O7 thin films on X-cut LiNbO3 single crystals. The use of double CeO2/YSZ buffer layers allows a single in-plane orientation of YBa2Cu3O7, and results in superior superconducting ...
