摘　　要：Due to their unusual features in condensed matter physics and their applicability in optical and optoelectronic applications,three-dimensional Dirac semimetals(3D DSMs)have garnered substantial interest in recent years.In contrast to monolayer graphene,3D DSM exhibits linear band dispersion despite its macroscopic thickness.Therefore,being a bulk material,it is easy to make nanostructures with 3D DSM,just as one normally does with metals such as gold and silver.Among 3D DSMs,cadmium arsenide(Cd_(3)As_(2))is quite famous and considered an excellent 3D DSM due to its chemical stability in air and extraordinary optical response.In this review,advances in 3D DSM Cd_(3)As_(2)fabrication techniques and recent progress in the photonics of 3D DSM Cd_(3)As_(2)are given and briefly reviewed.Various photonic features,including linear and nonlinear plasmonics,optical absorption,optical harmonic generation,and ultrafast dynamics,have been explored in detail.It is expected that Cd_(3)As_(2)would share an excellent tunable photonic response like graphene.We envision that this article may serve as a concise overview of the recent progress of photonics in 3D DSM Cd_(3)As_(2)and provides a compact reference for young researchers.
