“Three examples of organic materials for photonic applications: ultrafast all-optical switching, light amplification and optical limiting.”
Photons as information carriers have the potential to meet the ever-increasing demands on bandwidth and information density in fields such as information and communication technology, biomedicine and computing. Organic semiconductors may be well-suited to such applications, thanks to their ability to transmit, modulate and detect light in an architecture that is low cost, flexible, lightweight and robust. I will talk about some recent work on ultrafast all-optical switching in polymer amplifiers, optical limiting using graphene oxide and the role of intermolecular interactions on photoluminescence quantum efficiency in single crystals.
