Abstract:

In this age of electronic warfare, directed energy research is of utmost importance in order to ensure national security, robust military defense systems and gain competitive edge in research worldwide. The primary objective of directed energy weapons is intentionally directing highly focused energy sources to damage targets such as missiles, vehicles, electronic and optical devices etc. The intentional directed energy impacts on electro-optic devices (EODs) by developing analytical predictive models through experimental data validation is explored in this project. Although pure optical interconnects are immune to disruptions from external energy sources or electromagnetic interferences (EMI), optical communication devices contain electronic circuitry and ports that remain susceptible to EMI. This dissertation focuses on modeling the behavior of a commercially available Mach-Zehnder modulator when subjected to EMI. The developed predictive models in this research can be utilized to assess the extreme limits of operations for EODs surrounded by adverse electromagnetic environments.

Biography:

Hasan received his B.Sc. In Electrical and Electronic Engineering in 2017 from Bangladesh University of Engineering and Technology, Dhaka, Bangladesh. He joined the UNM Optical Science and Engineering PhD program in August 2019. He received his M.S. in Optical Science and Engineering in 2022. Since 2020, Hasan has been working on developing predictive models of Electro-optic Modulators in extreme electromagnetic environments. In 2024, Hasan won first place in the OSE 40th Anniversary poster competition which was judged by national laboratory scientists.
