1. An electrical power converter, comprising:
first circuitry configured to deliver a first electrical signal;
an emitter configured to produce light in response to the first electrical signal;
an absorber configured to absorb at least some of the light;
a metallic coating that at least partially surrounds the emitter and the absorber and is substantially opaque to the light; and
second circuitry configured to produce a second electrical signal in response to the absorbed light, the second electrical signal being substantially proportional to the first electrical signal and being electrically isolated from the first electrical signal.
