Featured publications

• Generation of Nanoscale Anticounterfeiting Patterns on Silicon by Optical Trap Assisted Nanopatterning

  

  T.-H. Chen, Y.-C. Tsai, R. Fardel, C. B. Arnold, J. Laser. Appl. (2017) uses optical trap assisted nanopatterning to create unique security markings by taking advantage of statistical fluctuations when generating nanoscale features within the pattern.

• Non-spherical particles for optical trap assisted nanopatterning

  

  Y-C Tsai, R Fardel, M M Panczyk, E M Furst and C B Arnold, IOP Nanotech. (2013) studies the optical near-field effects of OTAN using non-spherical polystyrene particles.

• Multiphoton polymerization using OTAN

  

  K.-H. Leitz, Y.-C. Tsai, F. Flad, E. Schaffer, U. Quentin, I. Alexeev, R. Fardel, C. B. Arnold, M. Schmidt, Appl. Phys. Lett. (2013) uses a combination of multiphoton polymerization and OTAN for additive manufacturing of structures with nanometer resolution.

• Microbead dynamics in OTAN

  

  R. Fardel, Y.-C. Tsai, and C. B. Arnold, Appl. Phys. A (2012) uses high-speed microscopy to show that gas bubbles can be formed from the laser pulse during Optical Trap Assisted Nanopatterning (OTAN) resulting in temporary bead displacement during operation.

• OTAN multiphoton absorption polymerization

  

  Y.-C. Tsai, K.-H. Leitz, R. Fardel, M. Schmidt, and C. B. Arnold, Physics Procedia (2012) combines the strengths of multiphoton absorption and near field effects using optical trap assisted nanopatterning (OTAN) to generate sub 100 nm features.

• Laser direct-write parallel nanopatterns on rough surfaces

  

  Y.-C. Tsai et. al., IOP Nanotech. (2012) generates parallel nanofeatures on rough surfaces with vertical steps more than 1.5 μm and feature variation smaller than 4% using OTAN. A Brownian motion model is used to describe and predict the lateral positional accuracy of the system. | Full text | View at publisher

• Array-based optical nanolithography using laser trapped microlenses

  

  E. Mcleod & C.B. Arnold, Optics Express (2009) modifies the OTAN technique to include an array of optically trapped nanospheres capable of fabricating multiple identical nanoscale (~100 nm) structures in parallel using 355 nm light. Feature size uniformity and relative positioning accuracy better than 15 nm was demonstrated. | Full text | View at publisher

• Subwavelength direct-write nanopatterning using optically trapped microspheres

  

  E. Mcleod & C.B. Arnold, Nature Nanotechnology (2008) presents a novel laser direct write nanopatterning technique using an optically trapped microsphere as an objective lens. This method was used to create arbitrary patterns with feature sizes of ~100 nm (less than a third of the processing wavelength) and a positioning accuracy better than 40 nm in aqueous and chemical environments. Submicron spacing is maintained between the microsphere and the substrate without active feedback control. | Full text | View at publisher
