Summary: The article introduces a method for generating highly pure circular polarization fields using waveguide microring resonators, which achieve high circular polarization purity by taking advantage of the symmetries of the structure and radiated modes, and directly utilizing both transverse and longitudinal field components of the guided modes. This is of great significance for achieving high-fidelity control and measurement in atomic quantum systems.

Summary: Doublet discrimination is commonly achieved through pulse analysis of light scatter parameters, while fluorescence signals can also be used. Different pulse parameter combinations can be utilized to distinguish pulses from single cells and those from cells stuck together. Scatter discrimination can be challenging when studying activated or proliferating cells. Using fluorescence measurement techniques for doublet discrimination in single cells is effective, especially for highly concentrated cell products and pathological specimens.

Summary: Soft and stretchable polymer optical waveguides have been increasingly used in wearable/implantable devices to address the mismatch between conventional optical waveguides and complex biointerfaces. However, challenges such as high optical loss and unstable signal transmission still exist during the implantation of flexible polymer optical waveguides.

Summary: In this study, single-crystal microrods and microplates of one-dimensional (DTA)(2)SbCl5.DTAC were successfully prepared with a 0D structure, exhibiting a broadband orange emission peak with a high photoluminescence quantum yield and a large Stokes shift under photoexcitation. The microrods showed an optical waveguide effect with low loss coefficient and linear polarized photoemission.

Summary: Cell identification and analysis are crucial in many biology- and health-related applications. Optical microscopy cannot provide clear images of the complex internal and surface structures of cells. This study investigates the effects of probing laser wavelength on label-free cell identification using single-cell angular laser-light scattering patterns (ALSP). Machine learning analysis reveals that the backward scattering direction is best for characterizing surface roughness, while the forward scattering direction is best for differentiating the number of mitochondria. Red or green laser light performs better than blue light in distinguishing surface roughness and the number of mitochondria.

Summary: This manuscript presents a 3D-printing based microfluidic device for light scattering imaging of single cells, with rapid fabrication and efficient hydrodynamic focusing capabilities. The device demonstrated effective confinement of cells in the center stream along the channel, and reliable results were obtained when tested with standard beads. The collected light scattering images matched well with simulation results, indicating the potential applicability of this device for fast, label-free detection of single cells.
