No IDC DURIP Harmonic mixer and multiplier chains for characterizing integrated terahertz optoelectronics
Abstract
This DURIP proposal aims to provide the required equipment and capabilities for thecharacterization of chip-scale terahertz devicesand systems. Using the proposed harmonic mixerand multiplier chains, we will conduct basic research on quantum well (QW) semiconductorheterostructures as a novel backbone for monolithically-integrated terahertz optoelectronicsystems. QW semiconductor structures have unique physical properties that enable monolithicintegration of optical oscillators, amplifiers, waveguides, modulators, photoconductors,photodetectors, and control electronics. Additionally, QW semiconductor structures arecompatible with metal-semiconductor field-effect transistor designs, enabling the realization ofcontrol electronic circuits side-by-side the terahertz optoelectronic devices on the same chip. Weplan to utilize the great physical properties of III-V QWs to realize a monolithically integratedterahertz optoelectronic platform, to enable chip-scale terahertz imaging, spectroscopy, andcommunication systems, for the first time.The requested harmonic mixer and multiplier chains allow on-chip measurement of the generatedand detected terahertz radiation power and spectral properties, with a large dynamic range andover a frequency range exceeding 1 THz. This proposal discusses the specifications oftherequested harmonic mixer and multiplier chains and their impact on the success of the proposedresearch and research-related education currently funded by DoD. This DoD research is currentlyfunded by the Office of Naval Research grant titled Integrated Terahertz Emitters and Detectorsbased on Quantum Optical Materials, awarded to the PI under the supervision of Dr. KevinLeonard (Contract number: N00014-22-1-2531). The impact of the harmonic mixer andmultiplier chains requested in this DURIP proposal is not only limited to the proposed research.They would also complement and upgrade the existing facilities available at the PI#s laboratoryand UCLA, enabling new basic andapplied research directions focused on ultrafast electronicdevices for various terahertz and submillimeter-wave imaging, remote-sensing, computation, andcommunication applications.
