Paper Abstract
A novel modified electro-optic Ti:LiNb01 lx2 directional coupler modulator is demonstrated. The modulator consists of a single-mode input waveguide which branches into a pair of optically coupled single-mode waveguides. Due to the symmetry of the modulator configuration, the half-power 3-dB operating point is automatically achieved without the need for a DC bias voltage. It is compatible with an efficient push-pull traveling wave type electrode structure for ultra high speed operation, utilizing the largest r33 electro-optic coefficient. In addition, the device can be used as a lx2 optical switch, requiring a lower drive voltage than a conventional directional coupler switch.
