High-efficiency ultraviolet inscription of Bragg gratings in microfibers
IEEE Photonics Journal, 2012 In this paper, we demonstrate high-efficiency inscription of Bragg gratings in microfiber. Strong Bragg gratings are easily inscribed using a 193-nm excimer laser and phase mask in microfiber drawn from the 62.5/125- μm standard multimode fiber ...

An investigation of chirped fibre Bragg gratings Fabry-Perot interferometer for sensing applications [PDF]
, 2005 Fibre interferometer configurations such as the Michelson and Fabry-Perot (FP) have been formed using uniformed and chirped Fibre Bragg Gratings (FBG) acting as partial reflectors. As well as increasing the dynamic range of the interferometer, chirped

Laser &Photonics Reviews, EarlyView.This work demonstrates a high‐fidelity stability transfer from an optical reference to a high‐repetition‐rate microcomb using a mode‐locked laser bridge. By employing electro‐optic sampling timing detection, femtosecond‐level synchronization and 10−18‐level fractional frequency stability are achieved.
