Nonclassical statistics of intracavity coupled ${\chi }^{(2)}$ waveguides: the quantum optical dimer

M. Bache, Yu. B. Gaididei, P. L. Christiansen

A model is proposed where two ${\chi }^{(2)}$ nonlinear waveguides are contained in a cavity suited for second-harmonic generation. The evanescent wave coupling between the waveguides is…
