Semiconductor lasers have very broad applications; they can be mass produced and easily integrated. Semiconductor lasers have found a widespread use as pumps for solid state lasers and are also heavily integrated into long distance fibre optic communication systems. They also have many other applications including use in CD/DVD players, laser printers, environmental sensors and barcode scanners. These lasers are so widespread because they are relatively inexpensive, robust, compact, easy to control and easy to operate.
In this project, new designs are investigated to produce high power devices. The fabrication of the lasers is carried out within the state-of-the-art facilities of the ACT Node of the Australian National Fabrication Facilities. In addition, another project investigates the chaotic behaviour in semiconductor lasers to develop a new automated chaos data analysis protocol. These protocols can then be used in systems for secure communications and also in financial transactions.
