Abstract: A semiconductor device is disclosed for environment heat conversion in coherent electromagnetic energy by a super radiant quantum decay and a thermal excitation of a system of electrons in a super lattice of n-i-p-n transistors with quantum dots on the two sides of the i-layer, and potential barriers for separating the quantum transition n-i-p regions from the adjacent conduction n and p regions. When an electron current is injected in a perpendicular direction on the transistor arrays, a super radiant field is generated in the plane of these arrays, with a power mainly obtained by a heat absorption that is much larger than the absorbed electric power. The device also includes an input heat absorber, and an output Fabry-Perot resonator with total transmission for the electromagnetic energy extraction from the device active region.

Abstract: A system is disclosed comprising a package of active Fabry-Perot transmitters and an electric charge accumulator for converting a part of coherent electromagnetic power in electric power at the proper voltage of this accumulator. An active Fabry-Perot transmitter is a semiconductor device comprising a packet of p-i-n diodes with double quantum dots on the two sides of the i-layer, separated by potential barriers from the conduction regions. The semiconductor structure is placed in a Fabry-Perot cavity with total transmission. While a resonant coherent electromagnetic beam is crossing the Fabry-Perot cavity, a small part from the electromagnetic energy is captured by resonant electron excitations through the i-layer, injecting an electron current in the device.
