Abstract
A dispersive optical waveguide device comprising an array of curved silicon rib waveguides providing optical paths in parallel between a first optical coupler at one end of the array and a second optical coupler at an opposite end of the array. The ends of the array waveguides adjacent to the second coupler are distributed around a first arcuate edge of the second coupler forming part of a first circle. A plurality of connecting waveguides terminating at a second arcuate edge of the second coupler face the first arcuate edge of the second coupler. The second arcuate edge forms part of a second circle having a radius of curvature which is half the radius of curvature of the first circle and has its perimeter coincident with the perimeter of the first circle adjacent the ends of the array waveguides.
