Summary: This paper investigates the resonant coupling phenomenon in resonant cavities and reveals the same excitation factors of resonant coupling under different environmental perturbations. The resonant coupling characteristics of middle-order modes are analyzed through experiments, and a preferential coupling model is proposed. This research is important for understanding and controlling resonant coupling in cavities.

Summary: Volumetric solar evaporation has great potential in various applications such as clean water production, desalination, and wastewater treatment. However, the efficiency of current volumetric solar evaporation is still low, and there is a need to explore new strategies for improving it. In this study, ATO@C nanofluids were used to achieve a high evaporation efficiency of 88.6% by adjusting the mass fraction and reducing the thickness.

Summary: In this study, the optical absorption properties of subphthalocyanine (SubPc) coupled to metallic optical cavities are analyzed both experimentally and theoretically. The research investigates how different electronic transitions of SubPc couple to optical cavity modes, with distinct spectral and directional light-harvesting features observed. Modeling allows for distinguishing between parasitic and productive absorption and estimating expected losses in a solar cell acting as an optical resonator.

Summary: Frequency-stabilized mid-infrared lasers are important for precision molecular spectroscopy, but complex stabilization schemes have limited their implementation. This study demonstrates optical self-locking of a quantum cascade laser to a two-mirror cavity, resulting in stable frequencies with significant linewidth reduction. Additionally, two-photon cavity-enhanced absorption spectroscopy of an N2O overtone transition near a wavelength of 4.53 um was successfully carried out.
