Nonlinear Dynamics of Two-State Quantum Dot Lasers under Optical Feedback
Photonics, 2021 A modified rate equation model was presented to theoretically investigate the nonlinear dynamics of solitary two-state quantum dot lasers (TSQDLs) under optical feedback. The simulated results showed that, for a TSQDL biased at a relatively high current,

Polarization-controlled anisotropy in hybrid plasmonic nanoparticles
Nanophotonics, 2022 Anisotropy has played a critical role in many material systems, but its controllable creation and modulation have been a long-lasting challenge for the scientific communities. Polarization-addressed anisotropy appears more attractive among all approaches

Structure of catalase determined by MicroED [PDF]
eLife, 2014 MicroED is a recently developed method that uses electron diffraction for structure determination from very small three-dimensional crystals of biological material. Previously we used a series of still diffraction patterns to determine the structure of lysozyme at 2.9 Å resolution with MicroED (<xref ref-type="bibr" rid="bib26">Shi et al., 2013 ...

Protein structure determination by MicroED [PDF]
Current Opinion in Structural Biology, 2014 In this review we discuss the current advances relating to structure determination from protein microcrystals with special emphasis on the newly developed method called MicroED. This method uses a transmission electron cryo-microscope to collect electron diffraction data from extremely small 3-dimensional (3D) crystals.
