Classification: CPC G | IPC G

Claim 18:
19. An optical switch comprising:
an input port to couple light into the optical switch;
a Mach-Zehnder interferometer comprising a first arm and a second arm and a phase shifter on the second arm to apply a phase shift to the light to form phase-shifted light, the phase shifter comprising a first dielectric electrode and a second dielectric electrode, the second dielectric electrode being separated from the first dielectric electrode by a gap, the phase shifter further comprising a waveguide structure electrically connected to the first dielectric electrode and the second dielectric electrode, the first dielectric electrode and the second dielectric electrode being controllable to apply an electric field within the waveguide structure, the waveguide structure comprising a material having a first dielectric constant in a direction, the first dielectric electrode and the second dielectric electrode comprising a second dielectric constant in the direction that is greater than the first dielectric constant in the direction, and the first dielectric electrode and the second dielectric electrode being separated along the direction; and
one or more output ports to output the phase-shifted light from the optical switch.
