N2 - Future telecommunication and data center networks as well as quantum optical communication systems will require optical modulators with wide bandwidths, large extinction, low operating voltage, and small size. We report the first quantitative demonstration of slow light enhancement of the electro-optic (EO) coefficient in a χ⁽²⁾ ferroelectric waveguide at microwave modulation frequencies. This is demonstrated in a compact (1 mm) photonic crystal device with a voltage-length product (Vπ· L) of 0.66 V-cm at 10 GHz and measured electro-optic modulation out to 40 GHz.
