Trapping nanoscale particles in a stable and non-destructive way is of great importance to life sciences. Near-field optical tweezers are a common way to trap nanoparticles. Here we propose and dem…
In this paper, we propose the CO 2 laser polishing method to prepare a novel type of incline plane-shaped long period fiber grating (IPS-LPFG) for strain measurement. This structure is achieved by …
A novel refractometer based on multimode fiber (MMF) embedded single mode-no core-single mode (ME-SNS) fiber structure is presented and investigated in detail. The ME-SNS structure has a higher ref…
