OPTICAL COMMUNICATIONS RESEARCH @ UNSW
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.
