Multi‐Soliton Microcombs Enable Ultrafast Nanometric‐Precision Ranging and Photon‐Level Detection

Advanced Science, EarlyView.
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.

Taper Embedded Phase-Shifted Fiber Bragg Grating Fabricated by Femtosecond Laser Line-by-Line Inscription

IEEE Photonics Journal, 2018
We demonstrate a phase-shifted fiber Bragg grating with a taper induced by femtosecond laser micromachining. In this configuration, a fiber taper fabricated by an arc discharge in a fiber splicer was sandwiched between two fiber Bragg grating sections ...

An optical fiber tip micrograting thermometer

, 2011
An ~12 µm long Bragg grating was engraved in an ~5 µm diameter optical fiber tip by focused ion beam (FIB) milling. An ~10-dB extinction was achieved at 1570 nm with only 11 indentations.

In Situ Disentangling Local Thermal and Photoelectron Contribution in Photoelectrochemical Reactions Based on Optical Microfiber Sensors

Advanced Science, EarlyView.
An in situ optical microfiber sensor capable of real‐time decoupling of photothermal and photoelectronic effects in photoelectrochemical reactions is presented. The approach utilizes highly sensitive modal interference to dynamically capture localized thermo‐optic signals from photothermal materials, thereby enabling quantitative discrimination of ...

Performance analysis of peak tracking techniques for fiber Bragg grating interrogation systems

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
In this paper, we propose a spectral correlation-based technique for tracking the wavelength shift of a fiber Bragg grating. We compared this approach, by means of a Monte Carlo numerical simulation, to the typical peak tracking techniques applied in ...
