Abstract

High speed photonic links require optical filter with high quality factor and free spectral range in GHz range. Such requirements motivate us to explore the characteristics of new configurations with various types of optical components and tuning mechanisms. In this work, different structures of dispersive elements are investigated to monitor the filtering scope of a microwave photonic link. The spectral characteristic of the optical filter is demonstrated in terms of normalized intensity and free spectral range. This study focusses on the various configurations with multiple number of optical components under test to reduce the ripple in the pass band of optical filter and to get linear phase response for distortion less transmission. The possible power tuning mechanism of the proposed structure is explained through various coupling coefficient and Mach-Zehnder interferometer structure. This helps in the design of tunable optical filters. Furthermore, the investigated elements are implemented in the design of optoelectronic oscillator for the generation of arbitrary shaped microwave signal. The chirping capability in the generated signal is introduced for energy efficient transmission of the signal in modern radar systems. The overall model is theoretically analyzed, and results are demonstrated through MATLAB simulations. The performance analysis of proposed optical components is demonstrated through microwave photonic link in Opti-System.
