Abstract

In this contribution we report on a direct visualization of CDT using an optical realization of the quantum-mechanical driven double-well Hamiltonian based on two tunneling-coupled waveguides with a sinusoidally-curved axis. Our experimental implementation makes it possible for the first time to directly trace the wave function evolution in the driven double-well potential by exploiting the fluorescence pattern observed in an active erbium-ytterbium:glass waveguide.
