I am Muhammad Sarkawi, a doctoral student at the Graduate School of Science and Engineering, University of Toyama, under the supervision of Professor Hideki Kuramitz. My research focuses on developing an optical chemical sensor based on Planar Lightwave Circuit–Attenuated Total Reflection (PLC-ATR) technology for real-time environmental monitoring. This study aims to integrate optical engineering with environmental science to detect pollutants, such as dyes and phosphate, directly in water, thereby contributing to sustainable water management and pollution prevention.
The PLC-ATR sensor combines the advantages of Planar Lightwave Circuits, which enable low-loss light transmission, and Attenuated Total Reflection, which allows sensitive detection through light–matter interactions on the sensor surface. By enhancing the sensor’s selectivity and response to various analytes, my study aims to develop a multifunctional, high-sensitivity sensing platform that supports both scientific and societal applications. Through this research, I aim to advance innovative environmental monitoring technologies that align with global sustainability goals.
