Abstract

In this letter, an innovative silicon-based metastructure (SBMS) is proposed for second harmonic generation (SHG) to enable the detection of refractive index (RI) and coronavirus disease 2019 (COVID-19) solution concentrations (SC). Utilizing the transfer matrix method (TMM) for analysis and computation, RI sensing is achieved, unveiling the sensitivity of SBMS towards variations in COVID-19 SC. Subsequently, a model correlating COVID-19 SC with the frequency of the second harmonic wave (SHW) transmission peak (TP) is established. Specifically, SBMS demonstrates a RI sensing detection range from 1.1 to 1.4, with a sensitivity of up to 16.946 THz/RIU and an optimal quality factor of

$1.66 \times 10 ^{\mathbf {5}}$

. Additionally, the relevant values for COVID-19 SC detection are 0 mM to 525 mM (where M is molarity, and 1 M =1 mol/L), 0.71225 THz/M, and

$1.66 \times 10 ^{\mathbf {5}}$

. The SBMS not only provides an important theoretical foundation for the development of novel virus detection technologies but also expands new possibilities for the application of SBMS in the biomedical field.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
