Abstract: An all-optical one-by-N optical switch is provided that has fewer components, is easier to control and has fewer optical losses that prior art one-by-N optical switches. An optical switch of the present invention includes an active deflection element formed from an electro-optical material to deflect an optical input from a single input to a selected one of N outputs. In one embodiment of the present invention, a single active deflection element at the input deflects an optical signal across a waveguide that commonly connects the N outputs. The N optical outputs include passive optical elements that are aligned with the deflected optical signal to accept a signal and provide it to a selected optical output. The optical switch can either be monolithic, where the optical material are all electro-optical materials, or can be hybrid, having separately formed components, such as the common waveguide, adhered to the substrate on which the optical switch is formed.

Abstract: A board level optical system for high speed device interconnection is disclosed. A constant intensity laser is mounted on a board substrate, and the laser light is divided into a plurality of optical channels using a waveguide splitter that is integrated into the substrate. An array of high speed optical modulators electrically driven by an IC device mounted on the substrate creates a corresponding plurality of optical signals. A connector is used to transfer the optical signals to one or more other devices, either on or off of the substrate. The optical modulators are preferably Mach Zehnder modulators comprising polymeric electro-optical material. The modulator array may be integrated into the substrate. IC device may also have integrated photodetectors for receiving optical signals routed via the substrate. In addition to optical wiring layers, the substrate may have one or more electrical wiring layers.

Abstract: The intensity of signals in optical networks can be controlled using a variable optical attenuator (VOA). The present invention is a VOA that is particularly well suited for optical networks, for example to provide channel-by-channel normalization of gain control of wavelength division multiplexed signals. The inventive VOA includes a waveguide having a cladding that includes an electro-optical material and electrodes that produce an electric field within the electro-optical material when a voltage difference is applied to the electrodes. The VOA also includes a layer that is parallel to the core of the waveguide and that optically couples to the core to receive light from the attenuated signal. A power meter receives light from the layer as an indication of the amount of light attenuated from the signal and for controlling the voltage to the electrodes.

Abstract: A system and method is provided for attenuating a light signal. One embodiment includes a method for causing optical attenuation in a waveguide, where the waveguide has an input port for receiving a light signal and an output port for output of an attenuated light signal. First, an electric field is generated in at least a portion of the waveguide, such that a first refractive index in that portion of the waveguide is changed to a second refractive index. Next, the light signal in the waveguide is directed from the input port to the output port through the electric field. And lastly, the light signal is attenuated as a function of the electric field. The light signal may be attenuated, for example, by changing the deflection angle, changing the beam collimation width or from emitting part of the light signal from the waveguide before the light signal reaches the output port.
