Greater than 90nm continuously wavelength-tunable fibre Bragg gratings

, 2003
We report silica-based fibre Bragg grating filters with wavelength tuning-spans well over 90nm using a simple set-and-forget beam bending tuning-package.

Pulse retiming based on XPM using parabolic pulses formed in a fiber Bragg grating [PDF]

, 2006
We experimentally demonstrate a novel all-optical all-fiberized pulse retiming scheme incorporating parabolic pulses generated in a linear fashion through pulse shaping in a superstructured fiber Bragg grating. The scheme relies on chirping the signal to

Uniaxial Strain‐Driven Ferroelastic Domain Tuning in LaAlO3${\rm LaAlO}_3$

Advanced Science, EarlyView.
The present work demonstrates based on AFM, μ$\umu$‐Raman spectroscopy, XRD, and first‐principles, that uniaxial strain provides a handle for tuning the ferroelastic domain populations in lanthanum aluminate, driving a continuous and controlled phase transition from a four‐variant rhombohedral crystal system to a two‐variant orthorhombic crystal system

Low Threshold Vertical Cavity Surface Emitting Lasers Based on CsPbI3 Thin Films

Advanced Science, EarlyView.
The first vertical‐cavity surface‐emitting laser (VCSEL) based on CsPbI3 thin films is fabricated by planar hot pressing. By optimizing the cavity design through optical gain assessment and rigorous coupled‐wave analysis, the VCSEL achieved an exceptionally low lasing threshold of 2.8 µJ cm−2.

A simple method for fabricating phase-shifted fibre Bragg gratings with flexible choice of centre wavelength [PDF]

, 2009
A simple technique for fabricating phase-shifted fibre Bragg gratings (PSFBGs) without the use of a phase-shifted phase mask is presented. Two, 3-mm long, standard fibre Bragg gratings (FBGs) were inscribed sequentially in singlemode fibre at the same
