Photonic Integrated Circuits(PICs) are futuristic technology which allows secure, cost-efficient, ultrafast data transfer and energy saving with a dynamic operation(i.e. In-Situ Energy Conversion, Energy Transfer). Existing PICs are limited to the passive data transfer phenomenon and have severe brittleness issues that restrict the inorganic materials from working efficiently. Our group work mainly focused on the flexible(elastic/plastic), active/passive organic crystal-based waveguides to enhance the capability of functioning. Self-assembly techniques used to grow these organic crystals show unique properties of polymorphism, reconfigurability and flexibility.
