Abstract

Recently introduced femtosecond laser printing approach was applied for the controlled fabrication of single germanium microparticles (MPs). The characterization of MPs was performed by scanning electron microscopy and near-IR optical spectroscopy. The size of obtained MPs is about 1-1.5 μm while their shape is close to spherical. Theoretical calculations of MP scattering cross section were performed on the basis of Mie theory. It is shown that extinction spectra of Ge MPs possess sharp resonances in near IR spectral region, which are identified by means of multipole decomposition analysis.
