Abstract: A polarization-independent electro-optically switched directional coupler (60) utilizing reverse differential propagation constant control comprises an electro-optic material having at least a pair of waveguide channels (62, 64) within an interaction region and at least a pair of electrodes (30, 31; 32, 33) for selectively producing an electric field across the waveguide channels which electro-optically alters an optical propagation constant of the waveguide channels so as to vary the effects of an optical coupling between the waveguide channels. The waveguide channels have a curvature region defined by a constant radius that is selected so as to coincide a set of operating voltages for an optical switch state of the directional coupler for a transverse magnetic (TM) polarization mode with a set of operating voltages for an optical switch state of the directional coupler for a transverse electric (TE) polarization mode by shifting the optical switch state of the TM polarization mode relative to the optical switch state of the TE polarization mode due to the relative difference between the magnitude of the electro-optic effect for the TM polarization mode light signal in the curvature region and magnitude of the electro-optic effect for the TE polarization mode light signal in the curvature region.

Abstract: A system for tuning an integrated optical switch element (100) utilizes a reflected portion (212) from a light signal (204) that is propagated into a first input port (106) defined on one side of an interaction region (110) of the optical switch element. The reflection occurs beyond an opposite side of the interaction region from the side on which the light signal is introduced. The reflected portion (212) is detected at a second input port (108) of the optical switch element (100) on the same side of the interaction region (110) as the side on which the light signals are introduced. The reflected portion (212) is used to tune the optical switch element (100) to a desired switch state by minimizing the reflection detected at the second input port (108). By minimizing the reflected portion (212) detected at the second input port (108) for a desired switch state, the strength of the optical signal (204) through the wave guide channels (206, 208) intended to be used to propagate the light signal in the desired switch state is maximized. As a result, the switching extinction ratio for the optical switch element (100) in the desired switch state is optimized. The system can be used to selectively tune a single optical switch element, or can be used to selectively tune multiple integrated optical switch elements that form an optical switch matrix on a common substrate, for example.

Abstract: A fiber optic ribbon cable has optical connector assemblies and release elements manufactured in line with the ribbon cable assembly so as to provide a fixed, lateral spacing of the optical fibers relative to each other within the connector assembly and has the remaining portion of the cable manufactured whith an arbitrary lateral spacing of the optical fibers relative to each other. A pair of adhesive tape layers are sandwiched around the optical fibers, release elements and in-line optical connector assemblies. The release elements provide access points to the optical fibers for easy application of a connector in the field. To equip the cable with a connector, the cable is cut near the midpoint of one of the access points. After the cable is cut, the adhesive tape layers and the release element may be easily peeled back exposing the optical fibers.
