Abstract
Apparatus for mode coupling in a waveguide that includes an engagement substrate arranged for intimate contact with a waveguide, and at least two actuators coupled to the engagement substrate and operative to create an interference pattern in the engagement substrate for producing a periodic deformation of the waveguide.
Claims16
Apparatus for mode coupling in a waveguide comprising:
- an engagement substrate arranged for intimate contact with at least one waveguide;
- and
- at least two actuators coupled to the engagement substrate and operative to generate acoustic waves propagating across said at least one waveguide, thereby to create an interference producing a spatially transverse periodic deformation in said at least one waveguide, said periodic deformation providing said mode coupling,
- wherein said at least two actuators and said at least one waveguide are generally aligned in the same plane.
