Abstract

We report on a feedback optical power control technique applied to fiber powering active sensors. The active sensor consists of one laser: a 1310nm Fabry–Perot laser or a 1550nm distributed feedback laser. In order to power up these elements, a remote high-power laser operating at 1480nm was used. Light conversion to electricity was achieved using indium phosphide photovoltaic cell proper to operate from 1000 to 1600nm. Results show that the proposed control system provided sensor optical power with variation less than 0.2dB when the temperature changed from 23 to 100°C or for fiber link attenuation variation from 0 to 10dB.
