Abstract
We demonstrate a phase shifter based on a silicon
slot waveguide infiltrated with liquid crystal. We achieve a phase shift of 73pi for a 5V drive voltage, with a voltage-length product of 0.022V.mm around 1V. We can drive the phase shifter directly with a 1V, duobinary pulse-width-modulated signal, allowing direct digital CMOS control of an analog optical phase shifter. Related Research Topics
