While the geometry of photonic integrated circuits can be characterized by existing means, their optimal and accurate performance requires detailed characterization of the light propagating within them. Researchers in Israel demonstrated the direct visualization of the light as it travels inside photonic integrated circuits. They used the natural nonlinear optical properties of silicon to directly map the electric field of the waves guided inside the integrated circuits, characterized waveguides and multimode splitters while extracting various parameters of the device. According to the researchers their work may be crucial component for the characterization of photonic circuitry, design fabrication and optimization… read more. Open Access TECHNICAL ARTICLE
