1. A system for wirelessly providing power and data to a remote device, the system comprising:

  • a source apparatus comprising;

    a light source for generating a modulated collimated beam;

    a steerable optical element; and

    a wireless uplink receiver; and

    a remote device comprising;

    a receiver for receiving modulated light from the modulated collimated beam and converting the modulated light into an electrical power component and a signal component, the receiver comprising a photovoltaic cell and a splitter for splitting the output from the photovoltaic cell into an electrical power component and a signal component;

    a processing unit for processing a signal component of the modulated light;

    a power conditioning unit for conditioning electrical energy from the power component for powering the device;

    an illumination detector for determining an illumination of the optical signal reaching the receiver and aligning the collimated beam; and

    an uplink channel in communication with the wireless uplink receiver to relay feedback data related to collimated beam alignment to position the steerable optical element.
