Abstract

A silica waveguide employing an electrooptic Kerr material as a functioning cladding is shown to modulate light at RF frequencies. The modulator uses a Kerr electrooptic material as the functional cladding on a silica waveguide structure. The modulator is designed to operate at 70 C and the electrooptic material has an index of refraction that is less than the silica waveguide at that temperature. Kerr-based materials have a refractive index that varies as the square of the applied voltage. This quadratic relationship is exploited by combining a DC bias voltage with the RF drive signal in order to reduce the drive voltage of the modulator.
