Patent US 20090007951 (US Patent Office, Jan. 08 2009)
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.
