Few-Layer Antimonene Decorated Microfiber as an All Optical Thresholder and Wavelength Converter for Optical Signal Processing

We experimentally investigated the broadband nonlinear optical response of highly stable few-layer antimonene (FLA) by performing a Z-scan laser measurement. FLA was deposited into the microfiber as a FLA-decorated microfiber, which is feasible not only for all-optical thresholding, but also for wavelength converting in optical signal processing.

1. Introduction

High speed optical signal processing is attracting lots of interest because of its importance in the optical communications. Since there is an increasing demand on the high speed, high capacity and high stability for the optical devices in the optical communication system, searching for suitable optical materials for the fabrication of linear and nonlinear devices has become a critical task in the field of optical signal processing.
