Centre for Micro-Photonics research to help boost telecoms

Friday July 16 2010

Recent research from the Centre for Micro-Photonics published in the Advanced Materials journal, has demonstrated how nonlinear nanophotonics principles can be applied to telecommunications structures to dramatically improve their speed and efficiency.

A recent publication in Advanced Materials by Centre for Micro-Photonics researchers Dr Baohua Jia, Dr Dario Buso, Dr Joel van Embden, Dr Jiafang Li and Professor Min Gu has shown that the addition of highly nonlinear quantum dots to 3D nano-structures has the capability to greatly enhance the nonlinear properties useful for telecommunications.

Featured on the front cover of volume 22, issue 22 issue, the paper entitled "Highly Non-Linear Quantum Dot Doped Nanocomposites for Functional Three-Dimensional Structures Generated by Two-Photon Polymerization explored the doping of Lead Selenide quantum dots into a photosensitive
organic–inorganic hybrid polymer that can then be structured into photonic crystals (PhCs) through the use of a femtosecond laser based fabrication system.

The resulting PhCs have a large third order nonlinearity that will allow the behavior of the crystal to be modified with a beam of light in much the same way as the presence of electrons can alter the behavior of a semiconductor. Higher nonlinearities allow for the crystal to change its properties with greater efficiency so that the high response time of the change is easier to realize in telecommunications systems.
