Abstract
An all-fiber phase modulator based on lead titanate zirconate coating depos ited by dc reactive magnetron sputtering was fabricated and optically chara cterized. The frequency response showed a flat broadband structure up to 60 0 kHz, with an efficiency of 0.73 rad/(V m). This is an order of magnitude higher than that for sputtered zinc oxide based phase modulators. Radial mo de resonance peaks were observed between 10 and 700 MHz, with a maximum pha se modulation amplitude of 0.3 rad at the fundamental radial resonance freq uency of 25.6 MHz.
