Patent number: 7595500Abstract: A detector includes a voltage source for providing a bias voltage and first and second non-insulating layers, which are spaced apart such that the bias voltage can be applied therebetween and form an antenna for receiving electromagnetic radiation and directing it to a specific location within the detector. The detector also includes an arrangement serving as a transport of electrons, including tunneling, between and to the first and second non-insulating layers when electromagnetic radiation is received at the antenna. The arrangement includes a first insulating layer and a second layer configured such that using only the first insulating in the arrangement would result in a given value of nonlinearity in the transport of electrons while the inclusion of the second layer increases the nonlinearity above the given value. A portion of the electromagnetic radiation incident on the antenna is converted to an electrical signal at an output.Type: GrantFiled: August 14, 2006Date of Patent: September 29, 2009Assignee: University Technology Center CorpInventors: Garret Moddel, Blake J.

Patent number: 7173275Abstract: A hot electron transistor includes an emitter electrode, a base electrode, a collector electrode, and a first tunneling structure disposed and serving as a transport of electrons between the emitter and base electrodes. The first tunneling structure includes at least a first amorphous insulating layer and a different, second insulating layer such that the transport of electrons includes transport by means of tunneling.

Patent number: 6835949Abstract: An assembly includes a device for receiving at least one input to produce an output. An antenna supports the device to transfer the input to the device and further to transfer the output from the device such that the antenna supports a selected one of the input and the output as a high frequency current. The antenna includes a peripheral configuration which confines high frequency current to at least one dominant path to oscillate therein. The other one of the input and the output is a lower frequency signal present at least generally throughout the antenna. At least one port is positioned away from the dominant path to isolate the lower frequency signal from high frequency current in the dominant path. The antenna is configured to support the lower frequency signal having a frequency in a low frequency range including zero to several terahertz.Type: GrantFiled: August 29, 2003Date of Patent: December 28, 2004Assignee: The Regents of the University of ColoradoInventors: Manoja D.

Patent number: 6756649Abstract: A modulator includes a voltage source, a first arrangement including first and second non-insulating layers configured such that a modulation voltage from the voltage source can be applied there across, and a second arrangement between the first and second non-insulating layers. The second arrangement includes a first amorphous layer configured such that a transport of electrons between the first and second non-insulating layers includes tunneling. The first arrangement further includes an antenna structure for absorbing part of an input radiation, while a remainder of the input radiation is reflected. The second arrangement cooperates with the first arrangement such that the antenna exhibits a first absorptivity, when a first modulation voltage is applied to the first arrangement, and exhibits a distinct, second absorptivity, when a second modulation voltage is applied, thereby causing the antenna to reflect a different amount of input radiation to an output as modulated radiation.Type: GrantFiled: January 20, 2003Date of Patent: June 29, 2004Assignee: The Regents of the University of ColoradoInventors: Garret Moddel, Blake J.
