High-Efficiency Optical Parametric Oscillator Based on Stimulated Brillouin Scattering Pulse Shaping
IEEE Photonics Journal, 2019 We present an optical parametric oscillator (OPO) that uses a pump pulse shape tailored by stimulated Brillouin scattering. The theoretical analysis is carried out for comparison between Gaussian pump and the step function pulse pump.

Effects of atmospheric turbulence on fiber-coupled DPSK system in Satellite-to-Ground downlink
Results in Physics, 2018 Fiber-coupled differential phase-shift keying (DPSK) modulation is potentially an effective approach for further high-speed satellite lasercom, due to the high detection sensitivity, low linewidth requirements, and uncalled-for complex phase-locked loop ...

Journal of Applied Physics, 2011 We present a generic microcavity platform for cavity experiments on optically active nanostructures, such as quantum dots, nanocrystals, color centers, and carbon nanotubes. The cavity is of the Fabry-Pérot type with a planar back mirror and a miniature concave top mirror with radius of curvature ∼ 100 μm.

Tunable pH Sensitive Lipoplexes
, 2023 To provide long circulating nanoparticles able to carry a gene to tumor cells, we have designed anionic pegylated lipoplexes which are pH sensitive. The reduction of positive charges in nucleic acid carriers allows reducing the elimination rate, increasing circulation time in the blood, leading to improved tumor accumulation of lipid nanoparticles ...
