1. An optical system, comprising:
a first substrate, wherein the first substrate has a first surface and a second surface opposite the first surface;
at least one light-emitter device disposed on the first surface of the first substrate;
a second substrate, wherein the second substrate has a mounting surface;
a lens coupled to the mounting surface of the second substrate;
an optical waveguide disposed on the mounting surface of the second substrate; and
a spacer coupled to the mounting surface of the second substrate, wherein the spacer is in physical contact with the at least one light-emitter device such that the at least one light-emitter device is optically coupled to the optical waveguide via the lens.
