Abstract: An electrical power converter can include a plurality of layers disposed on a substrate. An emitter, including a first semiconductor junction that is formed at an interface between a first pair of adjacent layers, can produce light in response to a first electrical signal. An absorber, including a second semiconductor junction that is formed at an interface between a second pair of adjacent layers, can absorb at least some of the light. Circuitry can produce a second electrical signal in response to the absorbed light. The second electrical signal can be substantially proportional to the first electrical signal and can be electrically isolated from the first electrical signal. Because the light can remain within the layers during use, the electrical power converter can have a higher efficiency than a comparable device that propagates the light through at least one interface between air and a semiconductor material.
