Large Scale Terahertz Systems: Sub wavelength Field and Sub picosecond Temporal Control for Programmable Terahertz Generation
Abstract
THz frequencies, between 0.1 3.0 THz, has shown game changing potential in a wide array of applications across sensing, imaging and communication from high resolution radars and imagers, chemical spectroscopy, contraband detection to ultra fast wireless communication. Traditionally, research efforts in this frequency range have focused on optimization of single devices for power generation or detection, either using solid state devices or photoconductive optics, generally with complex and bulky instrumentation and has been limited in its scope. In this proposal, we put forward a different approach and design methodology, one that focuses on harnessing the collective synchronized responses in an array of distributed mm sized Terahertz sensors and sources, either in 3D space or on large wafer scale arrays, thereby enabling large aperture area THz electromagnetic (EM) systems. Such coordinated response, which requires sub picosecond accuracies in synchronization, is expected to enable new distributed system functionalities in transmission, reception, distributed EM sensing, imaging, beam forming, localization and clock synchronization.
