Abstract
A fiber-optic magnetic-force phase modulator using an aluminium-jacketed current-carrying fiber coil placed in a uniform external magnetic field is presented. The modulator has a center frequency of 30 kHz with a modulation efficiency of 2.4 rad/mA and a Q of 4.6. A theoretical model is developed for the modulator, and its predictions are compared with experimental results. An accurate and simple method of characterizing the phase modulator response is described
