1. A device for optical signal processing, comprising:
a first layer, a lens being disposed within the first layer and adjacent to a surface of the first layer, wherein the lens is formed in a silicon portion of the first layer and comprises a plurality of anti-reflective coating (ARC) layers formed above a curved surface;
a second layer underneath the first layer and adjacent to another surface of the first layer; and
a waveguiding layer located underneath the second layer and configured to waveguide a light beam transmitted in the waveguiding layer, a grating coupler being disposed over the waveguiding layer;
wherein the lens is configured to receive, from one of the grating coupler or a light-guiding element, the light beam, and focus the light beam towards another one of the light-guiding element or the grating coupler.
