Claim:
1. An optical system, comprising: a semiconductor substrate comprising a plurality of trenches; an optical component comprising at least one lens and a plurality of grooves, wherein the plurality of grooves are formed on a same surface of the optical component; and a plurality of optical fiber stubs, wherein each of the optical fiber stubs is at least partially disposed in one of the plurality of grooves and one of the plurality of trenches, whereby the optical fiber stubs establish optical alignment between the at least one lens and an optical device disposed on the semiconductor substrate, wherein a first trench of the plurality of trenches includes a width that is less than a diameter of the optical fiber stubs and a second trench of the plurality of trenches includes a width that is greater than a diameter of the optical fiber stubs, and wherein a depth of the first trench is greater than a depth of the second trench.
