A laser-based thin-film processing scheme for printing and annealing of graphene oxide is reported. This method is able to print and simultaneously reduce the graphene oxide to graphene. The resulting graphene thin film is with good transmittance and its resistance is dramatically reduced from 200 MΩ to 80 KΩ.

We use Gaussian beam to position a microsphere in a polymer precursor environment near a substrate. Pulsed laser is focused by a microsphere to induce multiphoton polymerization in the near-field, enabling additive direct-write nanoscale processing.

Brillouin anti-Stokes signal is used to obtain the spontaneous Brillouin spectrum of an aluminosilicate fibre. The spectrum bears two prominent peaks separated by 340 MHz and exhibiting a temperature dependence of 0.7MHz/°C and 1.1MHz/°C.

We present the design of high-contrast sub-wavelength grating functioning as angularly selective filter for the transverse-mode-control of VCSELs. Highly angular dependent reflection characteristics can be obtained for avoiding high-order transverse modes in large-area VCSELs.
