Nanofabrication

Investigation of mechanisms of the femtosecond laser induced photo-polymerization in resins and resists. Comparison of two-photon absorption and avalanche rates in photo-polymerization of micro-optical elements and photonic crystal structures and templates. Future work will extend to the use of electron beam lithography for the fabrication of nano structures.

Research Overview:

The applied plasmonics staff are new to Swinburne and will develop their research interests throughout the year. Professor Juodkazis previous work has revolved around that mechanisms of femtosecond laser induced photo-polymerisation as well as the use of such methods in altering materials, such as the generation of birefringence.



Precise tuning of refractive index: PMMA structured by tightly focused 800 nm/150 fs laser pulses; numerical aperture of the objective lens was 1.4. Pulse energy: 50 (1), 40 (2), 30 (3), and 20 nJ (4); the pattern (4) has larger density of irradiation points. The birefringence is measured along the horizontal central cross-section.
