1 W Single‐Mode Large‐Area Edge‐Emitting Laser via Non‐Hermitian Spatial Mode Filtering

Laser &Photonics Reviews, EarlyView.
We demonstrate a non‐Hermitian spatial mode filtering approach for achieving high‐power single‐mode operation in large‐area edge‐emitting laser diodes. By symmetrically coupling passive filter arrays to the main lasing waveguide, higher‐order transverse modes are effectively suppressed while preserving the fundamental mode.

Visible Octave Frequency Combs in Silicon Nitride Nanophotonic Waveguides Driven by Ti:Sapphire Lasers

Laser &Photonics Reviews, EarlyView.
Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

160 Gb/s retiming using rectangular pulses generated using a superstructured fibre Bragg grating

, 2007
A 160 Gb/s retiming scheme incorporating a superstructured fibre Bragg grating for pulse shaping is demonstrated. Retiming is performed in a single step without wavelength conversion, and a substantial bit error rate improvement is ...

Quasi‐Distributed Static/Dynamic Strain Detection of Wind Turbine Blades Based on Fibre Bragg Grating Arrays Sensing

High Voltage
This paper presents a quasi‐distributed sensing method for wind turbine blade strain using fibre Bragg grating (FBG) arrays. The sensitive area of the blade strain variation is determined by simulation, and three fibre grating arrays are arranged on the ...

Differential phase tracking applied to Bragg gratings in multi-core fibre for high accuracy curvature measurement [PDF]

, 2006
High resolution quasi-static and dynamic curvature measurements are made by differential interferometric phase measurement of fibre Bragg gratings in separate cores of a multi-core fibre.

Side‐DBR Guided Exciton‐Polariton Lasing With Near‐Field Mode Imaging in an InGaN Thin‐Film Ridge Waveguide

Laser &Photonics Reviews, EarlyView.
Room‐temperature lower‐polariton‐like lasing is realized in an InGaN/GaN thin‐film ridge cavity with lateral distributed Bragg reflectors. Near‐field optical microscopy distinguishes the transverse side‐DBR‐confined mode from a longitudinal photon‐like mode, while simulations reproduce their spatial profiles.
