    摘要： The present invention is an improved electro-optical device comprising a substrate-supported layer of electro-optical material disposed between upper and lower electrodes. Conventional practice has been to make the electrodes thick to minimize electrical loss. Applicants, in contrast, have discovered that the performance of the device can be improved by making the electrodes thin—typically about 2 microns or less and preferably about 0.5 micron or less. While the thin electrodes take a relatively large loss penalty at low frequencies, at higher frequencies the thin electrodes provide a relatively low loss, thus producing a flattened frequency response as compared with thick electrode devices. The device can maintain a wide operating bandwidth at frequencies of interest for optical transmission while reducing the required drive voltage.

    摘要： A first capacitor and a second capacitor are charged until voltage at the second capacitor settles to a settling voltage. While charging, the first capacitor is alternately switched between a current source and ground. When the settling voltage is reached, charging of the first capacitor is halted. The second capacitor continues to be charged until voltage at the second capacitor reaches a reference voltage. The amount of time it takes for the settling voltage to reach the reference voltage corresponds to a measure of capacitance on the first capacitor.

    摘要： Metamaterial structures are taught which provide for the modulation of terahertz frequency signals. Each element within an array of metamaterial (MM) elements comprises multiple loops and at least one gap. The MM elements may comprise resonators with conductive loops and insulated gaps, or the inverse in which insulated loops are present with conductive gaps; each providing useful transmissive control properties. The metamaterial elements are fabricated on a semiconducting substrate configured with a means of enhancing or depleting electrons from near the gaps of the MM elements. An on to off transmissivity ratio of about 0.5 is achieved with this approach. Embodiments are described in which the MM elements incorporated within a Quantum Cascade Laser (QCL) to provide surface emitting (SE) properties.

The control system includes a master controller and a plurality of devices. Each of the plurality of devices have a number of channels. Each channel has an identifying number and a plurality of channel states. The method includes at least initially directing one or more messages sent to and from each device to the master controller, sending a first type of control message from the master controller to respective devices, and sending a second type of control message and a third type of control message from the master controller to respective devices. A control message of the first type directs the respective device to place one of its channels in a specified channel state. A control message of the second type directs the respective device to set the level of a specified parameter to a certain value, and a control message of the third type comprises a character string of variable length.
