In this paper, an optical switch driven by the optical force is demonstrated based on Nanoelectromechanical system (NEMS) technology. The switch consists of a Mach-Zehnder interferometer (MZI) and a ring resonator. One of the MZI arms is suspended to enable optical switching by optical force induced displacement. The optical force is introduced by injecting a control light into the ring resonator...
Reported is an all-optical high-speed three-input logic AND gate using cascaded sum- and difference-frequency generation (cSFG/DFG) in a periodically poled lithium niobate (PPLN) waveguide. The converted idler wave via cSFG/DFG carries the AND result of the three-input signals. PPLN-based 40 Gbit/s three-input logic AND operations for both non-return-to-zero (NRZ) and return-to-zero (RZ) signals are...
