Abstract: Two-dimensional (2D) materials and van der Waals (vdW) heterostructures have shown tremendous potential for light detection applications, opening new avenues in developing novel, high-performance and broadband photodetectors (PDs) beyond state-of-the-art. A variety of high-performance 2D, hybrid-2D and vdW PDs with ultra-high responsivity, sensitivity and ultra-broad spectral response have been reported so far based on graphene, transition metal dichalcogenides (TMDs), III-VI group layered semiconductors, black phosphorous, and more, covering the visible, infrared and terahertz spectra. Nevertheless, the field is far from reaching its saturation. Quite the opposite, the rich portfolio of 2D materials and newly emerging physical phenomena in vdW heterostructures, together with favourable heterogeneous integration of 2D systems with silicon technology, CMOS read-out electronics and flexible platforms, set new horizons for the development of innovative 2D integrated PDs. In this talk, I will focus on graphene integration with silicon photonics for telecom applications and multispectral photodetection. Key aspects related to device physics, material properties, fabrication process development and system performances will be discussed..
