1. An optical device, comprising:
a first substrate defining:
a surface; and
a trench forming a depression along a portion of the surface;
a second substrate coupled with the surface and extending from the surface to form a raised portion around the trench;
a laser die positioned within the trench, such that the laser die is surrounded by the second substrate;
an optical material positioned within a region between the laser die, the first substrate, and the second substrate, the optical material comprising at least one of a liquid material or a solid material; and
