An assembly for optical to electrical power conversion including a photodiode assembly having a substrate layer and an internal side, an antireflective layer, a heterojunction buffer layer adjacent the internal side; an active area positioned adjacent the heterojunction buffer layer, a plurality of n+ electrode regions and p+ electrode regions positioned adjacent the active area, and back-contacts configured to align with the n+ and p+ electrode regions. The active area converts photons from incoming light into liberated electron hole pairs. The heterojunction buffer layer prevents electrons and holes of the liberated electron hole pairs from moving toward the substrate layer. The plurality of electrode regions are configured in an alternating pattern with gaps between each n+ and p+ electrode region. The electrode regions receive and generate electrical current from migration of the electrons and the holes, provide electrical pathways for the electrical current, and provide thermal pathways to dissipate heat.

A transmitter of a wireless power transfer and data communication system comprising a transmitter system including a transmitter housing, one or more high-power laser sources, a laser controller, one or more low-power laser sources, one or more photodiodes, a beam steering system and lens assembly, and a safety system. High-power and low-power beams are directed to corresponding receivers and transceivers of a transceiver system inside a remote receiver system by the controller and the beam steering system and lens assembly. Low-power beams include optical communication to the transceiver system. The photodiodes of the transmitter system receive optical communication from the transceiver system. Low-power beams are co-propagated with and in close proximity to high-power beams substantially along an entire distance between the transmitter housing and the receiver system. The safety system instructs the controller to reduce the high-power sources in response to detected events.
