Mach-Zehnder modulators are devices used in optical communication systems to convert electrical signals into light signals at high speed. Their performance depends on RF transmission line design, where signal loss, impedance matching, and speed alignment between electrical and optical signals all influence bandwidth.
A blog by Prashanta Kharel, Flexcompute explores how an autonomous design agent tests multiple electrode geometries, guided by design constraints, to balance these factors. Unlike a simple parameter sweep, the agent forms hypotheses, learns from results, and refines its approach across iterations, even correcting flaws in its own simulation setup along the way. It ultimately identifies a wide-cap T electrode design that comes closest to the desired combination of RF properties.
