Patent number: 5859614Abstract: A planar antenna for microwave applications includes a supporting structure that is made using standard LTCC (low temperature co-fired ceramics) multi-layer techniques and a polyimide tape containing an adhesive at one side which is adheringly attached to the supporting structure. The body of the supporting structure defines a transmission line substrate and several of the intermediate layers define a path for microwave energy to be coupled from the transmission line substrate to the antenna. The method includes adhering the tape to the supporting structure, cutting the tape to size, and baking the tape and supporting structure in an oven at about 180.degree. C. for about 4 hours to rigidify the tape. The obtained antenna is thus protected against substrate effects such as TM mode zero cut-off frequencies.Type: GrantFiled: May 15, 1996Date of Patent: January 12, 1999Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Arthur C.

Patent number: 5428225Abstract: An integrated optical intensity modulator. The modulator is an optical waveguide on a semi-insulating substrate and having a core layer for transmitting an optical signal. The modulator includes contiguous the core layer an active cladding which has a multicoupled quantum well structure. The multicoupled quantum well includes at least one pair of quantum wells separated by a barrier. The modulator further includes first and second additional claddings wherein the core layer and the active cladding are interposed between the additional claddings. A voltage source generates an electric field through the active cladding which varies the refractive index of the active cladding as a function of the strength of the electric field for modulating the optical signal.Type: GrantFiled: May 16, 1994Date of Patent: June 27, 1995Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Milson Silva, Peter R. Herczfeld, Steven A. Malone, Arthur C. Paolella

Patent number: 5304794Abstract: The present invention utilizes the internal photovoltaic effect of a GaAs SFET to mix an RF modulated optical signal with a microwave signal. As those skilled in the art will readily recognize, a GaAs MESFET generically comprises an n layer of GaAs (channel) deposited on semi-insulating GaAs (substrate). Source, gate and drain electrodes are then formed on the channel with the gate acting as a Schottky barrier. In this standard MESFET, the difference in doping between the channel and substrate produces a potential barrier. It has been found that when the device is illuminated, the potential barrier is reduced in the region between the source and the gate and drain and the gate. This reduced potential barrier allows more drain current to flow from the device. It has been found that this drain current photoresponse is highly non-linear with respect the gate voltage applied to the device and therefore, it may be used to mix RF modulated optical signals with microwave signals.Type: GrantFiled: May 25, 1993Date of Patent: April 19, 1994Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Steven A.
