Technology developed to shape light for future technologies
Context: Technological Breakthrough in Nanophotonics
Researchers at IISc Bangalore have developed a cutting-edge platform for controlling light at the nanoscale, with significant applications in quantum communication, data encryption, and next-gen photonic devices.
Relevance : GS 3 (Science & Technology)
Technology: 2D Semiconductor Colloidal Quantum Wells (CQWs)
- CQWs are highly suitable as nanoscale photon sources due to their:
- Giant oscillator strengths
- Large absorption cross-sections
- These features make CQWs ideal for applications in quantum metrology and quantum cryptography.
Innovation: Integration with Dielectric Metasurfaces
- Dielectric Metasurface Resonators (MSRs) were integrated with CQWs to achieve:
- Emission line narrowing
- Long-range photon transport
- Enhanced spectral purity
- Platform used:
- Cadmium Selenide (CdSe)-based CQWs
- Silicon nitride (SiN) slab-waveguide
- Square-lattice geometry of holes for precise light emission tuning.
Important Results Achieved
- 12-fold increase in brightness
- 97% reduction in spectral width, ensuring superior spectral purity.
- Photon transport over 1 mm, a critical step for on-chip quantum devices.
Applications of the Innovation
- Quantum Communication – Highly secure information transfer.
- Quantum Cryptography – Ensuring data encryption using single-photon sources.
- Next-gen Photonic Devices – Efficient on-chip light sources for quantum information processing.
Tools and Setup Used
- Confocal Photoluminescence (PL) Microscope funded by DST-FIST program.
- Published in Advanced Optical Materials.
Future Plans
- Integration of Single Quantum Emitters (SPEs) with MSRs
- Potential for creating highly efficient single-photon sources.
- Could revolutionize on-chip quantum photonics for secure communications and advanced sensing technologies.
Significance for India
- Enhances India’s quantum technology ecosystem.
- Strengthens quantum cryptography capabilities.
- Opens new frontiers in nanophotonics research.
