博士 === 國立中央大學 === 光電科學研究所 === 96 === In view of the progress of wireless communications, the security of electromagnetic field is concerned by the mass population. Therefore, the EM Field detective technology will be respected gradually. The accurate EM Field detective system will be contributive to the study in biology and environment ecology. In this thesis, we focus on the research and develop the applications of Mach-Zehnder modulator with micro antenna in electrooptical electromagnetic sensors. We study the basic configuration of the no bias Mach-Zehnder modulator, high sensitivity electrooptical electromagnetic sensors and the packaged module of fiber coupling with electrooptical electromagnetic detective system. According to the experimental results, This integrated structure of electromagnetic field sensor can be potentially employed in electromagnetic measurement.
