Special Symposium on Opto Excitonic Devices

2D quantum materials have emerged as an attractive platform to investigate a plethora of quantum excitations such as exciton, magnons, phonons, among others. Excitons, quasiparticles that emerge from the Coulomb attraction between electron and holes have been long touted to be excellent carriers of energy and information. With the advent of 2D materials, robust excitons with large binding energy, spin-optic response and unprecedented light-matter interaction strength have been realized making possible device concepts a reality. This special symposium focuses on important technological breakthroughs that create potential pathways towards viable opto-excitonic devices based on 2D excitons. Specifically, we will address (I) Engineering the excitonic properties via strain, bias, and other external stimuli and (II) Excitonic device concepts such as switches, energy converters and sensors. 

Special Symposium on Photonics for Climate Change Mitigation Adaptation 

Photonics will play an increasingly important role as the world seeks sustainable technologies that can mitigates climate change. Photonics, especially sensing, will also be critical in understanding and predicting climate change impacts and in aiding how societies adapt to rising temperatures and changing environments.  Photovoltaics and LEDs for solid state lighting are famous examples of photonic devices that have had large measurable impacts in reducing energy consumption, but optical interconnects and networks, photonic approaches to neuromorphic and quantum computing (compared to classical computing), low emissivity coatings, indoor agriculture, and the use high power lasers for manufacturing are all areas where photonics may be important by reducing the amount of heat trapping gasses released into the atmosphere. Examples of photonic tools that are useful in obtaining information for understanding and adapting to climate change include remote sensing, LIDAR mapping, and imaging from drone or satellite of coastlines, agriculture, and the environment, as well as sensing for transportation and smart cities.

This symposium seeks papers that identify examples of where the use of photonics may result in significant energy savings to assist in the mitigation of climate change.  Ideally papers should attempt to quantify the energy savings. Papers are also sought that show how photonics may be useful in providing information for adaptation and planning for resilience in response rising temperature and changing environment.
