Dr. Christi Madsen, professor in the Department of Electrical and Computer Engineering at Texas A&M University, was named a 2023 fellow of the International Society for Optics and Photonics (SPIE) for her technical achievements in the multidisciplinary fields of optics, photonics and imaging, and for her service to SPIE and the optics and photonics community.
Madsen has contributed fundamentally to the architectures, design, implementation and application of multistage, tunable optical filters. Among many other technical accomplishments, she was one of the first to develop the theory for coupled ring-resonator filters and the first to implement such filters and experimentally demonstrate their flat passband and narrow transition regions using integrated optics. She was the first to design multistage optical all-pass filters and apply them to dispersion compensation in high-speed optical fiber communication systems. She also invented a general architecture for combining multistage all-pass filters within an interferometer and developed the associated theory.
For 30 years, Madsen has contributed to the field of optics and photonics. She is a fellow of the optics and photonics society, Optica; was a distinguished member of technical staff at Bell Labs, Lucent Technologies; and is the founder of Sunstrike Optics LLC.
Her research interests include photonic signal processing, integrated optics, optical filters, microwave photonics, polarization optics, optical ring resonators, and dispersion and high-speed optical signals.
