Abstract: A method for manufacturing an electro-optically coupled switch in accordance with the present invention requires a sequential reconfiguration of a layer of semiconductor material. To begin, a base member is created wherein the semiconductor layer is positioned on a layer of insulator material with the insulator material positioned between the semiconductor layer and a semiconductor substrate. In sequence, with a first etch, the semiconductor layer is etched to create waveguides on opposite sides of a slot. In a second etch, the slot is deepened to expose the layer of insulator material in the slot. With a third contact pad doping process, pads can be positioned on top of the layer of insulator material for electrical contact with the respective waveguides. Metal contacts can then be placed on the contact pads, the slot can be filled with an electro-optical polymer and, if needed, the polymer can be poled.

Abstract: An optical modulator for switching an optical signal of wavelength λ from one waveguide-electrode to another requires that both waveguide-electrodes be made of an electrically conducting material. Also, a non-conducting cross-coupling material fills a slot along a length L between the waveguide-electrodes. Importantly, cross-coupling material in the slot provides a separation distance xc between the waveguide-electrodes that is less than 0.35 microns. When a switching voltage Vπ is selectively applied to the waveguide-electrodes, a strong uniform electric field E is created within the cross-coupling material. Thus, E modulates the cross-coupling length of the optical signal by an increment ±Δ each time it passes back and forth through the cross-coupling material along the length L. Thus, after an N number of cross-coupling length cycles along the length L, when NΔ equals one cross-coupling length, the optical signal is switched from one waveguide-electrode to the other.

Abstract: An electro-optically coupled switch includes first and second waveguides which are aligned in parallel to each other, with a thin, flat layer of cross-coupling material sandwiched therebetween. A voltage source is provided to establish a strong uniform electric field that is oriented perpendicular across the entire layer of cross-coupling material between the waveguides. Incorporated with the voltage source is a switch for changing the electric field, to thereby alter the refractive index of the cross-coupling material for transferring the transmission of an optical signal from one waveguide to the other.
