Non-linear optical properties of Sb doped InSe4 chalcogenide films for optical switching applications

TiN/Ti3C2 heterojunction-based photonic device for optical Kerr switch

“…The all-optical Kerr switch is a simple and effective all-optical modulator that utilizes the nonlinear effect to change the polarization state of weak light by a strong control light, which has a picosecond switching response speed and can achieve a switching speed of more than 100 GHz. 32–34 Therefore, ultra-high-speed signal demultiplexing can be achieved by using picosecond pulsed light. 33 When picosecond pulse light is used as a clock signal, signal pulses with different time slots can be easily extracted to achieve ultrahigh-speed channel demultiplexing.…”
