New technique for fabricating organic photonic components
Researchers from the University of Hyderabad have received a patent for a method of manufacturing molecular single-crystal photonic microresonators
An Indian patent has been granted to two scientists from the School of Chemistry at the University of Hyderabad (UoH) for an invention entitled “Molecular Single-Crystal Photonic Micro-Resonators and Method of Fabricating Thereof.” Rajadurai Chandrasekar, a professor at the university, and his former PhD student, Vuppu Vinay Pradeep, reported the work for which they have received the patent in the journal Advanced Optical Materials.
Highly reproducible manufacturing of organic optical crystals with well-defined geometry and dimensions is important for realising industrially relevant all-organic microelectronic and nanophotonic components and photonic integrated circuits. According to the scientists, their invention provides microresonators comprising a molecular single crystal that are useful in numerous photonic applications.
The invention demonstrates focused ion beam milling as a method of fabricating molecular single-crystal photonic micro-resonators. The researchers say the technique can be used to create photonic devices such as resonators, waveguides, lasers, interferometers, gratings, couplers, modulators, beam splitters, photonic crystals, and photonic integrated circuits.
Chandrasekar named this technique of fabricating organic single-crystal photonic components “Crystal Photonics Foundry.”
