Time-Resolved Photoluminescence Spectroscopy and Imaging for Hybrid Materials and Nanophotonic Devices
Abstract
The research objective is to explore the physics and engineering of optical cavities and membrane printing processes for high performance photonic devices, especially membrane lasers, through hybrid integration of nano-scale materials (crystalline semiconductor nanomembranes and novel 2D materials) with photonic crystal and metamaterial cavities. To accomplish these research activities, it is critical to have a powerful analytical tool which can characterize heterogeneously integrated membrane structures and devices, on their structural, surface and interfacial, strain, and thermal properties. Funding is requested to purchase HAMAMATSU C11200 Time-Resolved Photoluminescence (TRPL) Spectroscopy system for material structural and optical characterization, as well as extreme photonic devices and integrated chip testing. TRPL spectroscopy can provide key information about essential photonic phenomena such as the relaxation process of an exciton, initial stage phenomena in photophysics and photochemistry by direct measurement of the ultra-fast light excitation process, critical to 2D materials quality, defect/and interface research, and extremely sensitive molecular lifetime study. The system uses a streak camera that can achieve a temporal resolution of 15 ps and a temporal resolution of 5 ps can be obtained through deconvolution processing. Time-resolved spectrum is acquired in a very short time since lifetimes are measured over multiple wavelength without scanning. This new system can drastically boost the nanoscale-related research and STEM education capabilities at UTA, and to attract more students from under-represented groups into STEM careers. It will provide critical research training in the area of nanophotonics, optoelectronic and electronic materials, devices and systems for undergraduate and graduate students participating on the related research projects. Having such highly trained individuals in the workforce is critical to the economic well-being of the United States in both defense-related and other commercial industries that compete in the global marketplace. Thus the equipment system proposed for purchase here will have direct and positive impact on the research training of both undergraduate and graduate students supported by this project in multi-disciplinary areas that are core of critical importance to DoD.
