Seven-Ring-Core Erbium-Doped Fiber for OAM-MDM Amplification

IEEE Photonics Journal, 2023
Orbital angular momentum (OAM) mode division multiplexing (MDM) amplification in a seven-ring-core erbium-doped fiber (7-RC-EDF) has been experimentally demonstrated, in which the 1st–4th order OAM modes within each core of the 7-RC-EDF can be ...

Microfiber evanescent-field photothermal gas detection using acoustic-induced mode-dependent frequency shift

Nanophotonics, 2023
In this study, we experimentally showcase the microfiber evanescent-field photothermal gas detection by exploiting all-fiber MHz-level frequency shift scheme. Based on the acousto-optic interaction effect, the low-frequency shifts of 0.9 MHz and 1.83 MHz

Optical‐fiber bundles [PDF]

The FEBS Journal, 2007
Optical‐fiber bundles have been employed as a versatile substrate for the fabrication of high‐density microwell arrays. In this minireview, we discuss the application of optical‐fiber‐bundle arrays for a variety of biological problems. For genomics studies and microbial pathogen detection, individual beads have been functionalized with DNA probes and ...
