ULTRAFAST OPTICAL SWITCHING DEVICE BASED ON BLACK PHOSPHORUS

摘要

A high-speed optical switching device using a black phosphor includes a first channel for generating a first laser, which is a continuous wave of a first wavelength; A second channel for generating a second laser which is a continuous wave of a second wavelength different from the first wavelength; A modulator for modulating the second laser generated in the second channel into a pump signal; A first tunable filter and a second tunable filter that change wavelengths of the first laser and the second laser, respectively; A directional coupler coupling the first laser and the second laser; And an optical element for controlling the first laser and the second laser coupled from the directional coupler using the non-linearity and small-mount operation of black phosphorus. Accordingly, the volume and size of the apparatus to be applied can be reduced, and the data processing speed can be improved.
