Abstract
The multichannel waveguide device includes an array of waveguides located in a plane. Each waveguide channel has a redirecting element for redirecting a guided wave out of said plane, or vice versa. The redirecting elements are staggered in the direction of the waveguides so as to transform a one-dimensional array of in-plane waves into a two-dimensional array of out-of-plane waves, or vice versa.
