Classification: CPC H | IPC H

Claim 15:
16. An optical system comprising:
a photonic chip comprising an optical component having a predefined height relative to a first surface of the photonic chip;
a semiconductor substrate having a second surface; and
a supermode filtering waveguide (SFW) emitter contacting the second surface and formed as a first portion extending from a second portion, the SFW emitter comprising:
a first optical waveguide disposed in the second portion;
a spacer layer;
a second optical waveguide disposed in the first portion and spaced apart from the first optical waveguide by the spacer layer, wherein the second optical waveguide is evanescently coupled with the first optical waveguide and configured, in conjunction with the first optical waveguide, to selectively propagate only a first mode of a plurality of optical modes; and
an optically active region disposed in one of the first optical waveguide and the second optical waveguide,

wherein, when the second surface contacts the first surface, one of the first optical waveguide and the second optical waveguide is optically aligned with the optical component in at least one dimension.
