ABSTRACT: The parallelism between diffraction and interference in optics and
quantum interference in Josephson junctions is discussed and studied in
details. The interdisciplinary character of the present work is highlighted
through specific examples. The Fraunhofer-like pattern of the maximum Josephson
current in a single Josephson junction and the periodic field dependence of the
critical current in two-junction and in multi-junction quantum interferometers
is analyzed and discussed in comparison with the homologous classical optical
phenomena.
