With an increase in internet traffic, both long distance fiber networks and short-reach interconnections in data centres demand large-capacity optical transceivers. To achieve the proper transmission distances, symbol rates, and modulation formats in optical transceivers, directly modulated lasers, Electro- Absorption Modulators (EAM), and Mach-Zender Modulators (MZM) are, respectively needed. Because it offers a small footprint, high bandwidth, and low power consumption, the EAM is a crucial component for data centre applications. The Multiple Quantum Well (MQW) based structures has applications in op- tical modulators and switches. How to make optical transceivers with EAMs smaller and less expensive is a crucial concern. In this paper various EAM is investigated. The Insertion Loss (IL) and Extinction Ratio (ER) is also investigated for various EAMs. The applications based on EAM is also presented.
