Description
Summary:Exploration of ultrastable 2D material‐based optical devices toward all‐optical signal processing is attracting rising interest. As a Group‐VA monoelemental 2D material, antimonene is becoming a promising nonlinear optical material owing to its outstanding optoelectronic advantages with long‐term stability. Herein, all‐optical signal processing based on the high optical nonlinearity of antimonene is first demonstrated. Few‐layer antimonene is fabricated and decorated on the microfiber as an optical device. The device can be applied as an all‐optical Kerr switcher with an extinction ratio as high as ≈12 dB and wavelength conversion of modulated high‐speed signals at a frequency up to 18 GHz. The findings indicate that such a few‐layer antimonene‐based photonics device is applicable in nonlinear optics, which can be potentially developed for the applications of next‐generation high‐speed optical communication. The first prototypical few‐layer antimonene‐based optical Kerr switching and wavelength converting device has been constituted. The few‐layer antimonene (FLA) is decorated onto a microfiber and is applied as an optical Kerr switcher with high stability and an extinction ratio as high as 12 dB and a wavelength converter with a conversion efficiency up to 63 dB. It can be anticipated that two‐dimensional FLA may be utilized as an excellent photonics device for high speed optical communication system.
