ABSTRACT:
The present invention provides an electro-optic ceramic material including lead, magnesium, niobium and titanium having a propagation loss of less than about 3 dB/cm and a quadratic electro-optic coefficient of greater than about 2×10−16m2/V2at 20° C. at a wavelength of 1550 nm. The present invention also provides electro-optic devices including an electro-optic ceramic material including lead, magnesium, niobium and titanium having a propagation loss of less than about 3 dB/cm and a quadratic electro-optic coefficient of greater than about 2×10−16m2/V2at 20° C. at a wavelength of 1550 nm. The materials and devices of the present invention are useful in optical communications applications such as intensity and phase modulation, switching, and polarization control.
