A system for generation of power using an apparatus in deep water is disclosed. The non-epitaxial contact and waveguide layer is formed of a conductive material and such that it has a recess therein and over the injection region. The alignment fixture is moveable along one axis that lies perpendicular to the face of the circuit breaker in order to compensate for variations between the plane of the face of the circuit breaker and the plane of the sheet metal enclosure surrounding the circuit breaker.
