A/Prof Madden currently leads research on the hybridisation of Chalcogenide, Tellurite, silicon nitride, and germanosilicate technologies for multifunctional integrated optical devices for sensing, communications, metrology and chip based ultrafast laser systems. He also contributes to research on the applications for and system design of high power ultrafast laser systems for nonlinear optics, multiphoton microscopy, and materials processing from the DUV to MIR. He is the ACT node leader for the Australian National Nanofabrication Facility Optofab node in Canberra focussed on high performance optical coatings, custom diamond turned optics, and integrated optical circuits. His research career spans the period from 1984 to the present in start-ups and multi-nationals before joining the Laser physics Centre in 2004, covering a diverse range of areas including Liquid Crystals, seven different materials systems for planar devices, all fibre devices, Hybrid integration, Bragg gratings and devices, planar tunable lasers, optical transmission systems and all optical networking, non-linear effects in SOAs and planar waveguide devices, advanced semiconductor processing techniques, high power laser processing systems, ultra-high performance optical metrology system development. The spectrum of work has covered fundamental science through to putting new high technology products into volume production and out onto the market.
