Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors with a sub-cycle precision. These electro-optic Fabry-Perot resonators will allow for precise control and observation of light-matter interactions, particularly in the terahertz (THz) spectral range. By developing a tunable hybrid-cavity design, and measuring and modeling its complex sets of allowed modes, the physicists can switch between nodes and maxima of the light waves exactly at the location of interest. The study opens new avenues for exploring quantum electrodynamics and ultrafast control of material properties.
