Velocity Matched Millimeterwave Electro-Optic Modulator
Abstract
This effort has resulted in the fabrication and demonstration of an optical phase modulator at RF frequencies as high as 64 (GHz while using a visible light source. This technique, which is extendable to higher RF frequencies and to longer optical wavelengths, uses a series of high dielectric materials, set at an angle, between the RF signal source to match the resultant velocity of the RF wave with the optical signal in the photonic waveguide. The coupling of the RF wave to the optical signal in the modulator is enhanced by plating resonant antenna structures onto the modulator substrate and electronically interfacing them with the modulator electrodes. This technique can also be applied to interferometric type modulators.... Modulators, Optical modulators, Optical devices, Microwave millimeterwave.
