The results presented here show for the first time the experimental demonstration of the fabrication of lossy mode resonance(LmR) devices based on perovskite coatings deposited on planar waveguides. Perovskite thin films have been obtained by means of the spin coating technique and their presence was confirmed by ellipsometry, scanning electron microscopy, and X-ray diffraction testing. The LmRs can be generated in a wide wavelength range and the experimental results agree with the theoretical simulations. Overall, this study highlights the potential of perovskite thin films for the development of novel LmR-based devices that can be used for environmental monitoring, industrial sensing, and gas detection, among other applications.
