AIP Student Night
AIP members and all students in Physics are invited to attend the AIP
2006 Student Night
Thursday, July 27th, 2006, at 7:30pm
in the Kerr Grant lecture theatre,
Physics building, University of Adelaide
(Note. Security restrictions require that entry to the building is supervised. It is therefore essential
that attendees arrive before 7:30pm. Entry will not be possible after this time.)
Postgraduate Physics students from South Australian Universities will talk about their research work:

“Thermal poling of soft glass micro structured fibers
(developing visible band fibre lasers)”
Second order nonlinear optical effects are typically forbidden in glass. However, there exists a method to encourage glass to exhibit these effects. This method, known as 'thermal poling', can produce nonlinearities comparable tothose in commercially available nonlinear crystals. For my thesis I am studying the effects of thermal poling on 'soft glasses' with a view to producing micro structured optical fibers that can be incorporated into infrared fiber lasers to generate visible band laser radiation. Through careful design of the micro structured fibers we can control the guidance properties of the fiber to maximise the efficiency of the nonlinear effects. This talk will cover some of more interesting aspects of my work.

"Modifying Surfaces to Build Better Sensors"
Atomic scale control is crucial for successful sensor fabrication. Our
group at Flinders is interested in a range of different surfaces to
build sensors on, but in each case the surface must be modified from its
native state so that the sensor architectures can be built on them.
Understanding what happens at this scale is therefore key to being able
to control and optimise each process involved in making the sensor. In
this talk I will describe what happens to graphite (which is very close
to a 'perfect' surface) when it is exposed to highly reactive plasmas of
hydrogen and methane.
The Silver Bragg medals, awarded to the best 3rd-year Physics student in 2005 in each University, will be presented during the meeting
