Modulator structures for radio-on-fiber applications

Abstract

Traditional electro-optic modulators are not optimized for bandpass applications such as radio-on-fiber delivery systems due to their limited electro-optic response. This paper presents a resonant electrode structure that can be employed in optical modulator designs to enhance the electro-optic response of the modulator over a narrow frequency band, and improve the performance of optical radio systems. A simple model of the structure is developed, and experimental results validating the model and illustrating the effectiveness of the structure are presented.
