Polarization properties of interferometrically interrogated fiber Bragg grating and tandem-interferometer strain sensors [PDF]
, 2006 Lead sensitivity in low-coherence interferometric fiber-optic sensors is a well-known problem. It can lead to a severe degradation in the sensor resolution and accuracy through its effect on the fringe visibility and interferometric phase.

Germanium‐Based Mid‐Infrared Integrated Photonics
Laser &Photonics Reviews, EarlyView.The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Applications of polymer optical fibre grating sensors to condition monitoring of textiles [PDF]
, 2009 Fibre Bragg gratings (FBGs) in polymer optical fibres (POFs) have been used to measure the strain in a woven textile. FBGs in both POFs and silica optical fibres were attached to a woven textile specimen, and their performance characterised.

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking
Laser &Photonics Reviews, EarlyView.Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Super-step-chirped fibre Bragg gratings
Electronics Letters, 1996 Concatenation of apodised gratings to form a super-step-chirped fibre Bragg grating structure is demonstrated for the first time. Using this scheme, gratings of arbitrary lengths may be constructed for a predetermined wavelength span.

Rapid characterization of the ultraviolet induced fiber Bragg grating complex coupling coefficient as a function of irradiance and exposure time [PDF]
, 2007 We report the application of optical frequency domain reflectometry and a discrete-layer-peeling inverse scattering algorithm to the spatial characterization of the UV induced complex coupling coefficient during fiber Bragg grating growth.

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.
