Seoul, South Korea - Recent collaborative research conducted by Seoul National University and Australian National University has resulted in the development of a new, more compact, and efficient nanolaser, as reported in the "Nature Photonics" journal. 

This advancement in laser technology could have substantial implications for optical and quantum information communication.

Why It Matters:

This development signifies a step forward in addressing the limitations of traditional laser devices, which were often more extensive and less efficient. 

Introducing a more compact and efficient laser system could revolutionize how we approach optical communication and quantum information technology.

The Key Points:

  • Professor Park Hong-Gyu from Seoul National University and Professor Yuri Kivshar from Australian National University led the research.
  • The newly developed nanolaser features a unique "photonic disclination cavity," which utilizes air holes in synthetically produced crystals to create rotating laser light.
  • The size of the newly developed photonic insulator is approximately 3.75 times smaller than earlier versions, with a 24-fold increase in efficiency.
  • The research findings were experimentally validated, demonstrating the presence of orbital angular momentum in optical vortices.

What They Say:

Professor Park Hong-Gyu highlighted the significance of this development in creating a novel laser structure, emphasizing its potential applications in high-density photon/quantum integrated circuits and its capability for precise control of light characteristics. 

This advancement, he notes, opens new avenues for research and development in optics and communication technology.
