Josephson fluxonic diode

A nonuniform magnetic field has been applied to a long Josephson junction to create two separated vortex and antivortex regions. Such a configuration is the Josephson version of the so‐called fluxonic diode, an electrical dual to the semiconductor p‐n junction diode. Volt‐ampere relations of a junction subjected to this magnetic field are compared with those obtained using a unidirectional magnetic field. The study, supported by simulation, shows a number of unique characteristics including rectification and fluxon injection across the junction. Both are necessary phenomena for realization of a bipolar transistor dual.
