Use of optical fiber to supply power for an electrical sensor or actuator is advantageous in applications where galvanic isolation between a control and remote unit is required or when immunity to electromagnetic interferences, intrinsic safety, small size, or light weight are needed. When a conventional sensor is equipped with an optical fiber, the sensor is called a fiber optic hybrid sensor (Gross, 1991; Ross, 1992); when the current conducting paths of a conventional system are replaced by optical fibers, the system is called a power-by-light (PBL) system (Landry et al., 1991). Optically powered sensors and actuators are advantageous, for example, in electric power plant instrumentation to provide galvanic isolation between a remote sensor or actuator unit and a control unit.
