Scanning Probe Lithography

Optical methods in nanolithography have been traditionally limited by Abbe’s diffraction limit. One method able to overcome this barrier is apertureless scanning probe lithography assisted by laser. This technique has demonstrated surface nanostructuring below the diffraction limit. In this study, we demonstrate how a femtosecond Yb-doped fiber laser oscillator running at high repetition rate of 46 MHz and a pulse duration of 150 fs can serve as the laser source for near-field nanolithography. Subwavelength features were generated on the surface of gold films down to a linewidth of 10 nm. The near-field enhancement in this apertureless scanning probe lithography setup could be determined experimentally for the first time. Simulations were in good agreement with the experiments. This result supports near-field tip-enhancement as the major physical mechanisms responsible for the nanostructuring.

Sol Gel Process

High quality Nd-doped single-mode fibers have been prepared by using a sol-gel process. The longest fluorescence lifetime measured was 520 μs in an Al: SiO2 glass fiber containing 0.47 wt.% neodymium oxide. An efficient neodymium fiber laser with a slope above threshold of 42% was successfully demonstrated with the sol-gel prepared Nd-doped single-mode fibers as a fiber laser oscillator.
