Makri’s Power Limiter Research Noted in Scientific Reports Article

Makri used a power limiter consisting of a nonlinear lossy layer embedded in two mirror layers. This setup provides a resonant transmission of a low intensity light and nearly total reflectivity of a high-intensity light.

Makri used a power limiter consisting of a nonlinear lossy layer embedded in two mirror layers. This setup provides a resonant transmission of a low intensity light and nearly total reflectivity of a high-intensity light.

A study co-authored by Graduate Research Assistant Eleana Makri and two other Wesleyan researchers is a topic of a Oct. 20 article published in Scientific Reports.

Due to the ultrahigh-speed and ultrawide-band brought by adopting photons as information carriers, photonic integration has been a long-term pursuit for researchers, which can break the performance bottleneck incurred in modern semiconductor-based electronic integrated circuits. The article states that “recently, Makri theoretically proposed the concept of reflective power limiter based on nonlinear localized modes, where a nonlinear layer was sandwiched by two reflective mirrors, thus increased the device complexity.”

The report is based on Makri’s study, titled “Non-Linear Localized Modes Give Rise to a Reflective Optical Limiter” published in March 2014. The paper is co-authored by Tsampikos Kottos, the Douglas J. and Midge Bowen Bennet Associate Professor of Physics; Hamidreza Ramezani Ph.D. ’13 (now a postdoc at U.C. Berkeley) and Ilya Vitebskiy (Sensors Directorate at the Air Force Research Laboratory, Ohio).

The same study was also highlighted in Washington, D.C. at the spring review meeting of the Air Force Office of Scientific Research (AFOSR) as one of the main research achievements in electromagnetics of 2014 that can potentially benefit the U.S. Air Force.
