“…From literature, Tan et al [1] have reported 1.5 LAEF with single nanogratings based plasmonic PD using gold material. Tan et al [14] have presented 1.2 LAEF with double gratings based photodetector using gold material at 900 nm top rst grating width and also proposed the high absorption device by embedding metal nanoparticles with nanogratings [15]. Masouleh et al [16] have obtained 1.56 LAEF at 1.4 µm using gold material for nanogratings with 450 nm SWA width and also compared the different plasmonic nanogratings pro le to enhance the light absorption in nanostructured device [17].…”

This era of high speed photonic system demand photodetectors to have large bandwidth, gain and improved light enhancement competence. Amongst the different light absorption enhancement methods being researched by the investigators, plasmonic has acquired increased attention in the last decades. Although single layer plasmonic supported metal semiconductor metal photodetector (MSM-PD) has been explored for higher light absorption efficiency, but exploration for double-layer structure is lacking in the literature. This paper presents the performance of plasmonic based photodetectors (PDs) with double layer of nanogratings optimized at wavelength of 1.4 µm for night vision applications. Proposed design of plasmonic supported photodetector with double nanograting reports Quenching factor (QF) of 92.14% and provides enhancement in light with the optimized height of subwavelength aperture (SWA) at 60 nm. This can be credited to fact that both top and bottom layer of grating contributes to light trapping.

“…Also, the elliptical nanograting increases the light transmission [22]. In some recent references, for enhancing absorption in the GaAs layer, either nanoparticles or nanowires are used to excite localized surface plasmon resonances [22,23]. In our previous work [24], we used the hybrid plasmonic effect to confine more light in the active layer.…”

A new metal-semiconductor-metal photodetector (MSM-PD) based on a hybrid plasmonic and extra ordinary transmission (EOT) phenomenon is proposed. In the designed structure, we demonstrate that light transmission is improved by means of a new shape of surface nanograting and by optimizing the physical parameters of the metal. In this work the optical transfer parameters are strongly interrelated and all the parameters are optimized and the light transmission is enhanced by 55 times compared to the reference structure. Furthermore, the output port of the subwavelength slit in the presented MSM-PD has a dual horn shape and improves absorption light in the active layer of the structure. Also, by filling this port with the same type of material as that of the active layer, the absorption becomes greater than before. Moreover, the confinement region of the light in the active layer is reduced by using the hybrid plasmonic effect and therefore, the probability of the photon absorption is 101 times greater than that of the reference structure. Thus, the transmission and absorption enhancement improves the quantum efficiency and the electrical response of the presented MSM-PD. A high performance new photodetector is identified as an ultra-fast MSM-PD and because of its thin film active layer can be used as a low-noise one.

“…Furthermore, in another study, it was suggested that instead of using a binary diffraction grating structure, the structure that uses the second diffraction grating layers of nanoparticles became operative [6]. The Plasmonic radiation in these NPs leads to improve the absorption coefficient.…”

Metal-Semiconductor-Metal is one of the photodetectors that uses in optical detection. The characteristic of these detectors is improved by Plasmonic Science. Some of these characteristics include higher sensitivity, greater efficiency and improved optical absorption coefficient. Our predictions and the numerical results show high absorption in plasma-based combination of Metal-Semiconductor-Metal photodetectors in embedded Nano-grating and Metallic nanoparticles. The results of the simulation using FDTD simulation software shows that by optimizing the Nano grating metal parameters and embedded metallic nanoparticles, higher electric field is obtained, leading to higher absorption compared with the conventional MetalSemiconductor-Metal detector. This higher absorption is because of the higher ability of embedded metallic nanoparticles in absorbing the light and scattering properties by conduction electrons via stimulated resonance light from metallic nanoparticles.
