A device including a plurality of epitaxial chips is disclosed. An epitaxial chip can have one or more of a light source and a detector, where the detector can be configured to measure the optical properties of the light emitted by a light source. In some examples, one or more epitaxial chips can have one or more optical properties that differ from other epitaxial chips. The epitaxial chips can be dependently operable. For example, the detector located on one epitaxial chip can be configured for measuring the optical properties of light emitted by a light source located on another epitaxial chip by way of one or more optical signals. The collection of epitaxial chips can also allow detection of a plurality of laser outputs, where two or more epitaxial chips can have different material and/or optical properties.
