Abstract

A dispersive optical device comprises an input optical coupler (20''); an input waveguide (10'') arranged to launch light into the input optical coupler at a launching position with respect to the input optical coupler; an output optical coupler; one or more output waveguides arranged to receive light from the output optical coupler; and a plurality of transmission waveguides (30'') arranged to receive light from the input optical coupler and direct it to the output optical coupler, the transmission waveguides generally converging towards the input optical coupler so that optical paths through the input optical coupler, which follow the axes of the transmission waveguides at their interface with the input optical coupler, intersect at an intersection point; in which the launching point is displaced from the intersection point in the direction of the axes of the input waveguide.
