Abstract:
1. An optical waveguide switch, comprising, a waveguide Mach-Zehnder interferometer, wherein the Mach-Zehnder interferometer has a first arm, a second arm, two input ports, and two output ports; a phase section on the first arm of the Mach-Zehnder interferometer, the said phase section is a length of optical waveguide capacitor; a magnitude section on the second arm of the Mach-Zehnder interferometer, the said magnitude section is a length of optical waveguide capacitor that is different from the waveguide capacitor of the phase section; the mobility of the carriers in the waveguide capacitor's charge storage volume is lower in the waveguide capacitor of the magnitude section than that of the phase section.
