A polarization-independent dual-peak narrow-band filter is proposed and demonstrated theoretically and experimentally, which is realized by using a helical long-period fiber grating (HLPG) but with a period small down to tens of micrometers. Unlike those excessively tilted fiber gratings (Ex-TFGs) or the conventional long-period fiber gratings (LPGs) but with a small period down to tens of micrometers where the generated dual-peak pairs (DPPs) are all of the strong polarization-dependence, the DPPs obtained in this study are of the polarization-independent, which is the first time, to the best of our knowledge, that the underlying mechanism for generation of the polarization-independent DPPs in transmission spectrum of the helical small-period fiber grating (HSPFG) has been revealed both theoretically and experimentally.

An efficient method allowing the flexible generation of the azimuthally/radially polarized (AP/RP) beam and the hybrid polarized vortex (HPV) beam has been proposed and experimentally demonstrated by using a thinned helical fiber grating (T-HFG) with an intermediate period. This is the first time, to the best of our knowledge, that such three kinds of cylindrical vector beams can be flexibly generated by using only one fiber component. The proposed method provides the potential application of the HFG to not only the laser processing but also the optical manipulator and the optical tweezer.

To generate the orbital-angular-momentum (OAM) modes at multiple wavelengths, which exactly fit with the dense-wavelength-division-multiplex (DWDM) channel grids, is important to the DWDM-based OAM mode-division-multiplex (MDM) fiber communication system. In this study, a full C-band covered and DWDM channelized OAM mode generator is firstly proposed and experimentally demonstrated, which is realized especially by using a broadband helical long-period fiber grating (HLPG) combined with a phase-only sampled multichannel fiber Bragg grating (MFBG). As a proof-of-concept example, the DWDM channelized two complementary 51-channel OAM mode generators have been successfully demonstrated, each of which has a channel spacing of 100 GHz (∼0.

It is well known that the quantitative phase information which is vital in the biomedical study is hard to be directly obtained with bright-field microscopy under incoherent illumination. In addition, it is impossible to maintain the living sample in focus over long-term observation. Therefore, both the autofocusing and quantitative phase imaging techniques have to be solved in microscopy simultaneously.

  • The study explores the regulatory role of glial-derived neurotrophic factor (GDNF) produced by enteric glial cells (EGCs) on enteric mast cells, which are implicated in inflammatory bowel disease (IBD).
  • GDNF was administered through adenoviral vectors in a mouse model of experimental colitis induced by DSS, showing significant inhibition of mast cell activation and a reduction in inflammation-related markers.
  • The findings suggest GDNF is a potential therapeutic target for IBD, indicating it facilitates important interactions between EGCs and mast cells, leading to improved disease outcomes.

High throughput screening of protein-small molecule binding interactions using label-free optical biosensors is challenging, as the detected signals are often similar in magnitude to experimental noise. Here, we describe a novel self-referencing external cavity laser (ECL) biosensor approach that achieves high resolution and high sensitivity, while eliminating thermal noise with sub-picometer wavelength accuracy. Using the self-referencing ECL biosensor, we demonstrate detection of binding between small molecules and a variety of immobilized protein targets with binding affinities or inhibition constants in the sub-nanomolar to low micromolar range.
