Jiaming Lyu, Shengyuan Shen, Lin Chen, Yiming Zhu and Songlin Zhuang, Frequency selective fingerprint sensor: the Terahertz unity platform for broadband chiral enantiomers multiplexed signals and narrowband molecular AIT enhancement, PhotoniX 4, 28 (2023).
Researchers from University of Shanghai for Science and Technology(USST) present a frequency selective fingerprint sensor utilizing cross slot metamaterials array. The FAFS can achieve frequency selective effect by changing cross slot length. The resonance wavelength is linear to the length. The structure parameters had been optimized for sensing.
Regarding multiplexing enhancement detection, the sensor operates within 0.95 - 2 THz, exhibiting enhancement of 7.3 times for chiral substrates. They applied the sensor to measure the absorption lines of chiral carnitine, yielding a result of the retrieved absorbance envelope with the peak values amplification to 24.1% and 30.3% (D-carnitine) and 30.9% and 25.2% (L-carnitine) at the frequencies of 1.39 THz and 1.72 THz.
They have also employed the FAFS to enhance the AIT's robustness. Through the interaction between broad linewidth of plasmonic metasurface resonance and narrow α-lactose monohydrate, the AIT effect can be observed in a broad pixel range from pixel 13 to pixel 23 and the maximum enhancement factor can achieve at least 7 times. FAFS can capture narrow absorption line of analyte regardless of thickness uncertainty of analyte and the robustness of AIT can be enhanced by covering large pixels range.
According to USST Professor Lin Chen, corresponding author for the article, this sensor may have potential applications in boosting and identifying THz narrow and broad fingerprint spectra with low cost.
The undergraduate studuent Yi Ma, has published his manuscript on Optics Communications. Congratulations!
