A Universal Testbed for Comprehensive Characterization of Metaphotonic Structures
Abstract
A comprehensive characterization testbed based on an ultrafast optical pump-probe static system is proposed for the real-time charac,terization and stimulation of reconfigurable integrated photonic nanostructures. The proposed testbed enables simultaneous stimulati,on of the reconfigurable material inclusions (with deep subwavelength features) using electrical, optical (or both) stimuli and char,acterization of the optical and optoelectronic properties of the resulting devices. The proposed testbed can be used for independent, material and/or device characterizations and (most importantly) the investigation of the real-time dynamics of reconfiguration in a, large class of reconfigurable nanostructures with different structural architectures and material inclusions. The high-level operat,ion of the proposed testbed is based on the optical excitation (using a pump beam) of an ultra-miniaturized nanostructure (e.g., for,med using a reconfigurable material, e.g.,a phase- change material) for reconfiguration of its optical properties while another opti,cal beam (i.e., the probe beam) monitors the input-output optical characteristics of the reconfigurable nanophotonic device. The pro,posed characterization testbed will facilitate several existing and pending DoD- funded projects. It will also be an enabling platfo,rm for the development of ultra-compact and low- power photonic and optoelectronic nanostructures for a large range of applications, (e.g., imaging, spectroscopy, signal processing, and computing), which can be the topics for new DoD-funded programs. The tool will, be also available to other research groups at the Georgia Tech campus and outside as a shared facility to enable further collaborat,ive efforts in the rapidly expanding fieldof nanophotonics.
