Abstract
Abstract In this paper, an ultrahigh sensitive light‐induced thermoelastic spectroscopy (LITES) sensor based on a trilayer ultrathin perfect absorber coated T‐head quartz tuning fork (QTF) is reported for the first time. The absorber is designed according to the streamlined theoretical framework based on admittance matching principles. The incorporation of Cr as the primary absorber and the dual‐layer anti‐reflection coating of SiO 2 and Si in the tri‐layer (Si‐SiO 2 ‐Cr) ultra‐thin perfect absorber enables high absorption across a wide spectral range. It results in a 93% absorbance of the 1530 nm laser by the QTF. This feature enhances the QTF's photothermal‐elastic‐electric conversion efficiency and…
