Development Of Josephson Junction Series Arrays For Synthesis Of Ac Voltages And Arbitrary Waveforms

Josephson junctions operated by short pulses make the synthesis of AC and arbitrary waveforms possible. Series arrays of intrinsically shunted SINIS and SNS Josephson junctions were developed and characterized for applications in this Josephson arbitrary waveform synthesizer (S: Superconductor, I: Insulator, N: Normal conductor). First measurements under pulse irradiation are presented.
