Mimicking photon propagation through two-dimensional waveguide array by a one-dimensional waveguide array.

Abstract

Photon propagation through 1D and 2D waveguide arrays has been explored for various applications in the fields of quantum optics and quantum information. In this paper, we show that an appropriately designed 1D waveguide array can mimic the photon propagation through a 2D array. This alternative design is enticing since fabrication of 1D arrays is relatively less burdensome than 2D arrays.
