Researchers have unveiled a novel imaging method that leverages the interaction between light, sound, and thermally induced changes in materials. This discovery identifies a previously unexplored contrast mechanism in optoacoustic imaging, which arises from small temperature-driven variations in electromagnetic properties. The new approach enhances imaging sensitivity and resolution, enabling precise visualization of tissue structures. This advancement holds significant promise for improving diagnostic accuracy and advancing biomedical applications, particularly in tissue characterization and disease monitoring.

Polarization of photons plays a key role in quantum optics and light-matter interactions, however, it is difficult to control in nanostructures. Here scientists reveal polarization control of photons using photonic molecules (PMs) composed of two coupled photonic crystal nanobeam cavities. With an evanescent wave coupling, PMs directly control the local optical field that couples with the emitter, indicating a high efficiency in polarization control and a significant potential for applications in spin-resolved cavity quantum electrodynamics.
