UoH receives Indian patent for Photonic Micro-Resonator Fabrication

UoH Photonic-Resonator Patent

HYDERABAD: An Indian patent has been granted to Professor Rajadurai Chandrasekar and his former PhD student, Dr. Vuppu Vinay Pradeep from the School of Chemistry at University of Hyderabad (UoH) for an invention entitled ‘Molecular Single-Crystal Photonic Micro-Resonators and method of Fabricating thereof’ for the term of 20 years. The patent was granted from the 23rd day of March 2022 in accordance with the provisions of the Patents Act,1970. The team has also filed a PCT/IN2023/050278 on 23/Mar/2023.

Patent for molecular single-crystal photonic micro-resonator

Highly reproducible manufacturing of organic optical crystals with well-defined geometry and dimension is important to realise industrially relevant all-organic microelectronic and nanophotonic components and photonic integrated circuits.

Uoh Patent Right Certification

The present invention provides micro-resonators comprising a molecular single crystal that are useful in a number of photonic applications.

The present invention demonstrates focused ion beam milling as a method to fabricate molecular single-crystal photonic micro-resonators.

The method of fabricating abmicro-resonator can be used to create photonic devices such as resonators, waveguides, lasers, interferometers, gratings, couplers, modulators, beam splitters, photonic crystals, and photonic integrated circuits.

Professor Rajadurai Chandrasekar named this technique of fabricating organic single-crystal photonic components as Crystal Photonics Foundry.
