Towards Room Temperature Optoexcitonic Devices for Data Communication and Processing

Abstract

The work focuses on preparing a platform for manipulating optically active excitonic states to demonstrate control over exciton flux. Such control is important for demonstrating a platform for next generation integrated optoexcitonic devices. Our aim is to create an energy gradient using the shift in energy bands associated with bathochromic effect due to the presence of external strain. Such energy gradient can enable controlled exciton drift towards lower energy states. The STIR program explored the feasibility to demonstrate a room temperature proof-of-concept device based on strain engineering, in a transition metal dichalcogenide (TMD) monolayer material system. By first converting a photon into an exciton that is two orders of magnitude smaller in size, and then manipulating the excitonic energy in space before remitting the photon, the work lays out an optoexcitonic device platform for next generation on-chip communication and processing.
