The rapid evolution of microwave fiber links-based analog and digital communication systems, and the need for higher speed and higher bandwidth to support the Wireless 5G applications have increased the need for linear optical, optoelectronic and photonic components. In this paper, we review the linearization techniques and requirements for photonic components as they pertain to their utilization in digital and analog photonic links and networks. In particular, we present our work on Linear Electric Field Optical Modulator for digital coherent optical communication applications, and a Linear Optical Frequency Discriminator for phase-modulated direct-detection applications. These devices have unique features such as: (i) multifunction, (ii) compact, and (iii) low complexity design. The intended application is for advanced Microwave Photonics Links (MPLs), and potentially for software-defined MPLs.
