Description

Research opportunities in Advanced Detectors Research in the Space Vehicles Directorate are extremely varied. Experimental and theoretical research focuses on new detector development in the ultraviolet to mm-wave wavelength range (currently specializing in infrared [IR] and longer); new detector capabilities such as wavelength tunability and polarization discrimination; detector interactions with external electric, magnetic, and electromagnetic fields; and detector performance enhancement with photonic crystals or metamaterials. We are currently concentrating on III-V semiconductor multiple quantum well, superlattice, quantum wire, and quantum dot heterostructures. We have begun investigating the possibilities of photonic crystals and metamaterials for THz and IR detection. Our main emphasis is on space-based applications of these new detector designs, so we will always be concerned with radiation hardness and high sensitivity in our studies. We mainly investigate single detector pixels, but we are also interested in full focal plane arrays. Our current research interests include (1) optical-spectroscopy studies such as absorption, photoluminescence, light scattering, and ultra-fast pump/probe transient spectra; (2) quantum-transport studies such as tunneling, drift, diffusion, and field domains; (3) interactions between quantum wells or dots and photonic crystal cavities; and (3) metamaterials for THz, with an eye towards IR. Available characterization equipment include Fourier-transform IR spectroscopy, magneto-transport and magneto-optical, deep level transient spectroscopy, femtosecond laser pump/probe, and all the equipment necessary to fully characterize detector dynamics and performance at cryogenic temperatures. We have extensive collaborations with universities around the country, especially the University of New Mexico, where we can obtain access to MBE machines, clean rooms, SEMs, and AFMs.
