Abstract
A power electronics assembly includes a cooling chip having a first subassembly and a second subassembly. The cooling chip includes a first metallization layer and a second metallization layer on a portion of a first surface of the cooling chip, an inlet through a second surface of the cooling chip opposite to the first surface, an outlet through the second surface, and one or more micro-channels extending between and fluidly coupled to the inlet and the outlet. The first subassembly includes a light source coupled to a first electrode and the first metallization layer, which provides a second electrode. The light source is configured to receive an electrical signal and operable to produce light in response to the electrical signal. The second subassembly includes one or more wide band gap semiconductor photonic cores acting as an electric switch positioned to receive the light produced by the light source.
