First Demonstration of Photonic Bandgap Guidance in Hollow-core Photonic Bandgap Fibres with Square Lattice Cladding
Photonic Bandgap Guidance Hollow-core Photonic Bandgap Fibres Square Lattice Cladding
2015/7/20
Square lattice with much higher node-to-strut ratio is promising for significantly extending bandgaps in hollow-core fibres. First such fibres are achieved here. Minimum loss of 67dB/km is demonstrate...
Simple Method to Measure the Third-Order Nonlinear Coefficient of Optical Fibres
Third-Order Nonlinear Coefficient Optical Fibres
2015/7/16
We report a new method to measure the third order Kerr coefficient of optical fibres. This method is based on the self-phase-modulation-induced spectral broadening of optical pulses.

Erbium Emission Dielectric Nanoparticles Doped Silica-Based Fibres
2015/7/30
To improve spectral gain properties of silica-based EDFA, we propose a new route by embedding Er ions into dielectric nanoparticles. Broadening of emission band and fibre characterizations are present...
Elliptical Core Polarization Maintaining Highly Nonlinear Fibres
Elliptical Core Polarization Maintaining Highly Nonlinear Fibres
2015/7/30
A new design for polarization maintaining highly nonlinear fibres is presented. High birefringence, high polarization extinction ratio, and good splicing properties are obtained.
Photonic bandgap fibres have a cladding that is carefully structured to reject light of certain frequencies and propagation constants. The light is therefore confined to a core that can even be made o...
