PHOTONICS AND OPTICAL COMMUNICATIONS RESEARCH @ UNSW

The Photonics and Optical Communications Group (POCG) started research on optical wave propagation in optical fibres in 1974, under the headship of the world-renowned Professor Anthony E. Karbowiak, then Professor Pak L, Chu. In early 1980's, the Group established the first optical fibre manufacturing facility in the country dedicated for research purposes. In 2010s we have established the new photonic fibre fabrication facilities. 

Since early years, the Group has been training both research and course work students and young researchers and performing cutting edge research in photonics and optical communications, with the strong support from the government agencies and private industries. 

The Group under Professor Chu was the first to develop the preform index profile measurement technique which is still used today. The Group has also developed the world's first non-destructive measurement method of stress distribution in optical fibre and preform. This method leads to the manufacture of stronger fibres. The Group also developed a far field method for measuring the spot size of a single mode fibre which is now being used world-wide. In the mid-1980's, the Group discovered the mutual interaction effect between neighbouring solitons which leads to an upper limit of the achievable fibre bandwidth. It was only in 1995 that other research groups in the world have verified experimentally the important significance of these methods. 

The Group also developed many theoretical methods of analysing the performance of various kinds of fibres such as the stress birefringence in polarisation-maintaining optical fibre, and the cut-off calculation of noncircular fibres using effective index method.

Currently under the leadership of Professor Gang-Ding Peng, the ongoing research work in the group includes fibre laser, optical fibre sensing, special silica and polymer optical fibres and devices, planar photonic and waveguide devices, photonic signal processing techniques etc.
