For optical purposes, lithographically produced micron patterns are transferred by plasma/ion etching, which is a traditional technology in microelectronics and other micron technologies. However, pattern transfer by atmospheric pressure plasma etching can help to save time and cost for a future sustainable production. Therefore, the pattern transfer of lithographic resist masks into fused silica using atmospheric pressure reactive plasma jets (APPJ) was studied as a new approach of micropatterning. First the etch rates of the potential masking materials, e.g. photoresists, as well as of fused silica as substrate are studied in dependence on the APPJ etching parameters, in particular on the gas composition (O2/CF4) and the dwell time of the APPJ tool's footprint. Typical etch rates of the masking materials are in the range of 140 to 370&amp;nbsp;nm·s−1 whereas the fused silica has a rate of 25 to 80&amp;nbsp;nm·s−1. The surface morphology of masking materials changes during etching and features additional nanoscale roughness and waviness. The surface roughness of the etched masking materials and the fused silica are 2 to 5&amp;nbsp;nm rms and 1.5&amp;nbsp;nm rms for etch depths of ∼3000&amp;nbsp;nm and&amp;nbsp;∼&amp;nbsp;600&amp;nbsp;nm, respectively. Finally, the pattern transfer by APPJ of a diffraction grating with a period of 15&amp;nbsp;μm, depth of 230&amp;nbsp;nm and a roughness below 2&amp;nbsp;nm rms into fused silica was demonstrated.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors></contributors><titles><title><style face="normal" font="default" size="100%">Simulation of optomechanical interaction of levitated nanoparticle with photonic crystal micro cavity</style></title><secondary-title><style face="normal" font="default" size="100%">Opt.

The considered cavity has a quadratically modulated width of the silicon wave guiding structure, leading to a calculated cavity quality factor of 8 × 105. An effective mode volume of approximately 0.16 μm3 having the optical field strongly confined outside the silicon structure enables optical confinement on nanoparticle in all three dimensions. The optical forces and particle-cavity optomechanical coupling are comprehensively analyzed for two sizes of silica nanoparticles (100 nm and 150 nm in diameter) and various mode detunings. The value of trapping stiffnesses in the microcavity is predicted to be 5 order of magnitudes higher than that reached for optimized optical tweezers, moreover the linear single photon coupling rate can reach MHz level which is 6 order magnitude larger than previously reported values for common bulk cavities. The theoretical results support optimistic prospects towards a compact chip for optical levitation in vacuum and cooling of translational mechanical degrees of motion for the silica nanoparticle of a diameter of 100 nm.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors></contributors><titles><title><style face="normal" font="default" size="100%">Rapid identification of pathogens in blood serum via Raman tweezers in combination with advanced processing methods</style></title><secondary-title><style face="normal" font="default" size="100%">Biomed.

Here, we extend this technique to label-free non-linear microscopy with chemical contrast using coherent anti-Stokes Raman scattering (CARS) through a multimode fibre endoscope, which opens up new avenues for instant and in-situ diagnosis of potentially malignant tissue. We use a commercial 125 &amp;amp;\#x00B5;m diameter, 0.29 NA GRIN fibre, and wavefront shaping on an SLM is used to create foci that are scanned behind the fibre facet across the sample. The chemical selectivity is demonstrated by imaging 2 &amp;amp;\#x00B5;m polystyrene and 2.5 &amp;amp;\#x00B5;m PMMA beads with per pixel integration time as low as 1 ms for epi-detection.&lt;/p&gt;</style></abstract></record></records></xml>
