As the graphene market develops, it will be important to highlight even more potential uses. Importance to Introduce Graphene into PhotodetectorsGraphene's unique absorption spectrum, which encompasses tetra hertz (THz), far-infrared (FIR), mid-infrared (MIR), near-infrared (NIR), short-wave infrared (SWIR), AND ultraviolet, visible, has been the subject of extensive research into its potential use as the primary building material in ultra-broadband photodetectors. The electronic data is then sent to the receiver made of a graphene photodetector, which is responsible for converting the optical data signal being received back into an electronic signal
