Abstract
We report on microwave emission experiments of Bi2Sr2CaCu2O8+y-single crystals at frequencies between 12 GHz and 95 GHz. Due to the intrinsi c Josephson effect these samples form series connections of typically 2000 contacts. For the first time we observed phase-locking of more th an 1000 junctions at 93.7 GHz in Bi1.8Pb0.2Sr2CaCu2O8+y single crystal s. Concerning the development of high frequency sources me report on f irst experiments on vertically structured thin films of Tl2Ba2Ca2Cu3O1 0.
