N. Gronbechjensen et Ja. Blackburn, HYPERRADIANCE FROM SOLITON OSCILLATORS SYNCHRONIZED BY CAPACITIVE OR INDUCTIVE COUPLING, Journal of applied physics, 74(10), 1993, pp. 6432-6434
The output power from coupled Josephson oscillators is investigated wh
en the junctions are operated in their single fluxon mode. We demonstr
ate that both inductive and capacitive coupling mechanisms can give ri
se to hyperradiance when the power is coupled out through a boundary r
esistor. Analytical expressions are derived from adiabatic perturbatio
n theory and excellent agreement is found between the analytical expre
ssion and numerical simulations.
