ABSTRACT

This paper reviews the research activities in Microwave Photonic component frequency characterization at Department of Electrical Engineering, Chiang Mai University. Optical detector frequency response calibration is based on a two-tone technique where the two-tone stimulus light is generated by a Mach Zehnder Modulator. We present a calibration system where standard Mach Zehnder Modulator is used instead of a high extinction ratio one. The two-tone light power is also controlled by an optical amplifier. Once the photodiode is calibrated, it can be used to measure frequency characteristics of other components such as directly modulated lasers.
