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: Electro-optical modulators are provided, wherein a passive Y-connection (101-103) is followed by an active phase shifter (104-108) which receives the modulation signal and is in turn followed by a 3 dB directional coupler providing the modulated signal. Highly sensitive modulators can thereby be produced.

Abstract: A multichannel integrated optics modulator is disclosed that generates one or more independently modulated scanning beams. The integrated optics modulator includes at least one waveguide channel provided on an electro-optic substrate, wherein the waveguide channel is divided into a write waveguide channel that extends to an output side of the substrate and a dead-end waveguide channel that terminates before reaching the output side of the substrate. Control signals are selectively applied to electrodes provided above the dead-end waveguide channel and the write waveguide channel to control the coupling of light from the write waveguide channel to the dead-end waveguide channel. Light is coupled out of the dead-end waveguide channel through the use of an absorber located above an end region of the dead-end channel. The integrated optics modulator is incorporated in a variety of scanner mechanisms.

Abstract: An optical waveguide cross-point switch capable of full broadcast and strictly non-blocking operation. The device has a matrix of a plurality of input waveguides and a plurality of output waveguides (MxN). A reflecting surface associated with each intersection may be selectively activated to direct an optical signal on the input line to the associated output line. The reflecting surface may also be employed so as to convert an MxN matrix into a 2(MxN) rearrangeable cross-point switch. Each waveguide is capable of switching a data rate of 10 Gb/s or more. For example, with eight wavelength channels used to impart optical signals to a 16x16 switch a data rate of 1.28 Terabits/second is achievable.

Abstract: A multi-branch digital optical switch (10) having three branch waveguides through which light may exit. The multi-branch digital optical switch includes a main waveguide (12), two side branch waveguides (16, 18), and one center branch waveguide (14). The two side branch waveguides diverge symmetrically from the center branch waveguide at angles which are sufficiently small to allow modal evolution through the switch to be substantially adiabatic. Electric fields are used to raise the index of refraction of one side branch waveguide above the index of the center branch waveguide and to lower the index of refraction of the other side branch below the index of the center branch waveguide. The switch has an extinction ratio of 700:1 (28 dB) between its two side branches.
