Due to its unique trivalent electronic configuration, boron features richer properties as well as higher chemical and structural complexities compared with its right neighbor carbon. Consequently, over a decade later than the exfoliation of graphene, borophene has just been experimentally demonstrated on certain metal substrates and under ultrahigh-vacuum conditions, which, however, limit its wide and in-depth experimental researches. Here, for the first time, by employing liquid-exfoliated boron nanosheets, all-optical signal processing application is explored based on its superior photo-thermal response. A stable all-optical modulator is presented, which shows significantly faster response speed and higher modulation efficiency compared with other 2D materials-based similar devices. Furthermore, boron nanosheets-based all-optical logic gating operations are also demonstrated. This work not only presents an excellent 2D material-based all-optical signal processing device, but also marks a significant step toward optical and photonic researches as well as device applications of 2D boron.
