Highly stable Fabry-Pérot fiber-optic modulation device based on the photothermal effect of V2C MXene

Perovskenes: two-dimensional perovskite-type monolayer materials predicted by first-principles calculations

“…By decreasing the number of layers from a multilayer to a monolayer a transition from an indirect to a direct bandgap occurs in this class of materials which causes a significant enhancement of their electrical and optical characteristics such as their photoluminescence properties. [26][27][28][29][30][31][32] Therefore, going from the bulk to the 2D limit of atomically thin materials may bring more intriguing properties that may be important technologically.…”

Integrated Fabry–Perot interferometer based on Er/Yb co-doped fiber for all-optical phase modulation

“…Compared with the former, the latter has the advantages of low transmission loss, large operating bandwidth as well as fast response speed [6] . Moreover, benefiting from the high photo-thermal coefficients of two-dimensional (2D) materials, such as graphene [7][8][9] , MXene [10,11] , and tungsten disulfide (WS 2 ) [12,13] , the combination of 2D materials and microfibers makes alloptical phase modulation possible. In the above schemes, the 2D materials are typically deposited on the surface of a microfiber, and then phase and intensity modulation of the optical signal can be achieved via further integration with a fiber Michelson interferometer (MI) and a Mach-Zehnder interferometer (MZI).…”
