1. A multichannel waveguide device comprising:
- an array of waveguide channels located in a plane;
each waveguide channel having a redirecting element for redirecting waves propagating in an in-plane direction to an out-of-plane direction, or redirecting waves propagating in an out-of-plane direction to an in-plane direction; and
said redirecting elements being staggered in the direction of said waveguide channels so as to transform a one-dimensional array of guided waves propagating in an in-plane direction in said waveguide channels into a two-dimensional array of waves propagating in an out-of-plane direction or a two dimensional array of waves propagating in said out-of-plane direction into a one-dimensional array of guided waves propagating in said in-plane direction.

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.

30. A method of making optical off-chip interconnects in a multichannel integrated waveguide device lying in a plane, comprising:
-
redirecting waves propagating in an in-plane direction in each waveguide channel to an out-of-plane direction, or waves propagating in an out-of-plane direction to said in-plane direction;
staggering a point of redirection for each said waveguide channel in the direction of said waveguide channels so that a one-dimensional array of waves propagating in said waveguide channels is transformed into a two-dimensional array of waves propagating in an out-of-plane direction and a two-dimensional array of waves propagating in an out-of-plane direction is transformed into a one-dimensional array of waves propagating in an in-plane direction within said waveguide channels; and
intercepting or generating said two-dimensional array of propagating waves with an off-chip device. - View Dependent Claims (31, 32, 33, 34, 35, 36)
