Smart Photonic Systems for Extremely Large Telescopes

Summary

Astrophotonics: work in a team that is developing cutting edge technologies for the new generation of extremely large telescopes.

Supervisor(s)

Professor Joss Bland-Hawthorn

Research Location

School of Physics

Program Type

Masters/PHD

Synopsis

The basic project is to be involved in the integration and testing of a new concept astronomical instrument. This instrument will be tested “on sky” at the Anglo-Australian Telescope (AAT) before being shipped off to an overseas location. It is expected that the student will be directly involved in the lab and AAT testing. The new astrophotonics labs are in the basement of the Physics Building. We are developing special fibres that suppress a large number of unwanted lines from the earth’s atmosphere. These fibres involve taper transitions (photonic lanterns) and parallel arrays of fibre Bragg gratings. We will assemble an optical test bench to focus light into these gratings. The light will be fed to an optical spectrum analyzer. We will test the stability of the equipment to stress, temperature and humidity. We will use different classes of light sources to establish the consistency and performance of the gratings. We will look at different ways of packaging the gratings for ease of transport. There are several other new photonic devices that we can test if time allows. These include a photonic spectrograph and an “imaging fibre” bundle, called a hexabundle.

Additional Information

This is a potential research area for an Honours or a PhD student. The work will be in collaboration with the world-famous Anglo-Australian Observatory here in Sydney and they offer a top-up scholarship. The student needs to have a good working knowledge of some area of science or engineering. The project will make use of optics design packages, will involve a trip to a major telescope and will involve some basic optics preparation and tests in the lab.
