9984896ChevilleA research program using optoelectronically generated pulses for imagingand characterization in the far infrared (FIR) spectral region will beintegrated into a curriculum providing research opportunities forundergraduate students. Research Career Goals: A technique for broad bandwidth imaging in the farinfrared spectral region will be developed based on phase coherentdetection of scattered radiation. Applications include biomedicalimaging, nondestructive evaluation, and noncontact semiconductorcharacterization. This new approach will address spatial resolution,sample limitations, and chemical content mapping. The proposed techniqueis based on the existing ability to generate well characterized pulses ofTHz radiation.?? Specifically the research program will:Increase the power available in a compact, reliable THz source by atleast two orders of magnitude through enhancement of existing technologies,and collaborative work on magnetically enhanced THz sources.Develop new sources including dipole antenna arrays to be integrated witha programmable phase modulator to generate optically steerable far infraredradiation. These array sources combined with electro-optic imaging systemswill generate free space electromagnetic waves with soliton-like propertiesand applied to applications inTHz tomographic imaging.Existing work utilizing a THz impulse range for direct scatteringmeasurements will be extended to measure inverse scattering using multiplesources and detectors.This proposal seeks to open an underutilized region of the electromagneticspectrum to practical engineering applications with profound impact acrossa wide spectrum of disciplines. Educational Career Goals: The thesis of the educational component of thisproposal is that most students lack practical preparation for the demandingand cross-disciplinary tasks required in research. A unique photonicscurriculum, based on a model implemented by the PI on a small scale forthree years, will be developed in which students will be given practicaltechnical skills during the freshman or sophomore years. This curriculumwill provide training in the cross-disciplinary area of photonics andspecifically:Make use of practical, hands-on research training in an apprenticeshipmodel, similar to the teaching hospital of medicine at the freshman andsophomore level. Introduce students at the junior level to photonics research through aproblem based learning laboratory course. Provide independent research opportunities for senior students. Use effective pedagogies for education including scaffolding,collaborative learning, and communities of research practice to targetunder-represented students in Science, Mathematics, Engineering, andTechnology (SMET) to improve retention. Particular efforts will be made torecruit women for the program. Be based on a structure that is easily exportable to other programs orsubject areas, involve the use of representatives from industry andeducational consultants for assessment, and provide for the disseminationof the developed educational materials.***
