281 The one dimensional series Josephson Junction Array (JJA) is a rich system for the study of nonlinear dynamics and the quantum behavior of the superconducting phase. This talk will review some interesting features of JJA’s in several regimes: The regime of classical linear electrodynamics, where a mode structure is found that can be engineered to give microwave “photonic band gaps”. The regime of classical nonlinear electrodynamics, where JJA transmission lines can be used to realize parametric amplifiers. And the regime of strong quantum fluctuations of the phase, where a Coulomb blockade of Cooper pair tunneling can be realized which bares a striking duality to the classical DC Josephson effect. One objective of the study of this later regime, is to realize the dual to the AC Josephson effect, which could enable a new quantum standard of electrical current.
