摘要

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.
