The current-voltage characteristics and Josephson radiation have been studied for a number of indium bridges as a function of temperatures. These results show strong deviations from the predictions of the RSJ model, even in the temperature regime where the bridge size is smaller than the coherence length. This is ascribed to non-equilibrium effects in and around the microbridge. In order to improve the applicability of the Josephson effect, coherent arrays of 2, 4 and 10 microbridges were investigated. The 10 microbridge array is a novel design which allows the bridges to be parallel-biased at dc (equal voltages) and series-biased at 9 GHz (high output impedance).
