Optical fiber gratings-based sensors for detection of microorganisms and other organic substances 5.1. Detection of microorganisms Microorganisms are found everywhere and can be detrimental or beneficial in nature.
The mutual enhancement of graphene with a grating silicon carbide substrate provides a higher responsivity compared to other mid-infrared graphene photodetectors. It indicates that grating-structured graphene photodetectors have better potential for future development in the field of infrared detection. Table 1.
Due to its diverse crystal configurations with varying bandgaps, Silicon Carbide (SiC) has been widely utilized by numerous researchers in the preparation of photodetectors. In this paper, we propose high performance tunable photodetector with graphene-based SiC grating structure.
We proposed the High-performance perfect absorption infrared photodetectors with garphene-based SiC grating microstructures. Compared with existing graphene-based photodetector with or without SiC structures, our structure has better performance.
Therefore, the optical fiber gratings can collaborate with sensitive-materials and nanoparticles with high refractive index (such as GeO 2 with refractive index of 1.991 ) and transmittance to prepare highly sensitive sensors for detection of organic substances. 6. Conclusion and future prospects
