1. An optical device comprising a substrate structure, wherein the substrate structure comprises:
- a first triangular facet characterized by a first planar surface;
a second triangular facet characterized by a second planar surface; and
three sidewalls connecting the first triangular facet and the second triangular facet, wherein,each of the three sidewalls comprises a first portion coupled to the first triangular facet and a second portion coupled to the first portion and to the second triangular facet;
each of the first portions is oriented orthogonal to the first triangular facet; and
each of the second portions is oriented non-orthogonal to the first triangular facet.
