Abstract

The operation of the integrated optics Pockels cell and its application as a high-voltage power system sensor are explained. The effects of the waveguide´s geometry on the intrinsic phase-difference of the device is investigated. Properly biased devices as short as 7 mm have been fabricated and tested. While the piezoelectric behaviour of the sensor-heads affects the useful bandwidths of these devices, samples with bandwidths on the order of 1 MHz have been fabricated. Also, devices capable of reproducing lightning impulses with front-times as short as 0.5 μs have been demonstrated
