Abstract
We report on a feedback optical power control technique applied to fiber powering active sensors. The active sensor consists of one laser: a Fabry–Perot laser or a distributed feedback laser. In order to power up these elements, a remote high-power laser operating at was used. Light conversion to electricity was achieved using indium phosphide photovoltaic cell proper to operate from 1000 to . Results show that the proposed control system provided sensor optical power with variation less than when the temperature changed from 23 to or for fiber link attenuation variation from 0 to .
