Research Topic Description, including Problem Statement:

Traditional telecommunications relies on RF technology for the transmission of information. Despite the age of this technology high data transfer rates and secure communications have been realized through clever technological innovation. With congestion of the frequency spectrum, increases in computing power, and materials science advancements these methods for secure communications are becoming less secure and one day may present a liability for the users. Progress in optical communication offers a solution to this problem through the use of non-linear optical (NLO) materials. When contrasted with classical absorption where, the absorption coefficient is independent of the light intensity, NLO materials absorption is described by higher order functions. Beyond the systems level, selection of materials that would allow for higher data transfer rates and more secure communications is essential for this technology to be successful. Recent advances in entangled two-photon absorption (ETPA) have shown organic materials possess high entanglement cross sections amenable to secure communication and are sensitive enough to be feasible to low light intensity. A significant advantage of these materials with respect to inorganic NLO materials is their ability to be tuned with atomic precision for the desired application. With the current technology, prototyping of proof-of-concept devices for ETPA should be carried out to further advance the field. This research topic will investigate materials and device designs for a filter that is transparent to entangled photons but absorptive to classical coherent photons.

  • Goodson III, T., Makiuchi N., Ogawa K., Kobuke, Y.; J. Am. Chem. Soc. 2008, 130, 17212-17213
  • Wasilelewski R. M., Forbes D.E.M., et. al.; Nat. Rev. Chem. 2020, 4, 490-504

Relevance to the Intelligence Community:

Prototyping an ETPA filter would set the Intelligence Community on a path towards better communications. If successful, it should provide a proof of concept device, which may advance current technologies.
