A fiber-optic voltage sensor based on the longitudinal Pockels effect in a Bi12TiO20
crystal is described. The use of a special backreflecting prism as a phase-retarding
element is shown to improve the sensitivity and temperature stability of the sensor.
A comparison between the temperature properties of the glass backreflecting prism and
that of a quarter-wave plate is derived. The sensor demonstrates temperature stability of
±1.5% from -20°C to 60°C and sensitivity of 0.145% per 1 Vrms at 850 nm without the use
of an additional temperature control channel.
