Online and Efficient Fabrication of Helical Long-Period Fiber Gratings
By taking the advantage of inherent core-cladding eccentricities in standard single-mode fibers, in this letter, we propose and demonstrate an efficient method to fabricate helical long-period fiber gratings (H-LPFGs) by directly twisting fibers.

Multi‐Soliton Microcombs Enable Ultrafast Nanometric‐Precision Ranging and Photon‐Level Detection
Our work first demonstrates dual‐multi‐soliton ranging and confirms its multifunctional capability. The method achieves ultrafast and nanometric‐precision measurement. For practical applications, we further extend the multi‐soliton states to photon‐level ranging.

Optically Heated Long-Period Grating as Temperature-Insensitive Fiber-Optic Refractive-Index Sensor
A temperature-insensitive fiber-optic refractive-index sensor based on optically heated long-period grating (LPG) is presented. The LPG is manufactured in a short section of cobalt-doped optical fiber (COF), which can be thermally stabilized through a ...

Long period fiber grating in two-core hollow eccentric fiber
Long period fiber gratings (LPGs) in a two-core hollow eccentric fiber (TCHF) have been demonstrated experimentally. Two LPGs have been fabricated into the respective core of the TCHF by a high frequency CO2 laser. The coupling characteristics in the TCHF-LPG have been studied using the coupling mode theory (CMT).
