Abstract

In this article, a novel MoS2 based wideband absorber is proposed that covers the whole visible spectrum. The structure is composed of a single MoS2 layer on top of a Si/SiO2 distributed Bragg reflector. Coupled Au Nanospheres are utilized on top of the MoS2 layer that broaden the absorption spectrum as a result of the coupling between the plasmonic modes of individual particles. By optimizing the geometrical features of the plasmonic Nano-antennas, a high absorption value reaching more than 80% in the range of 400–600 nm is obtained which decreases to 50% at 700 nm. The application of the proposed structure in designing a wideband visible light photodetector is discussed either.
