High power superluminescent light-emitting diodes
Superluminescent light-emitting diodes (SLEDs) are optoelectronic devices which combine different aspects of laser diode and LED performance. The device utilises a ridge waveguide structure to amplify spontaneously emitted light. Steps are taken to suppress feedback by minimising facet …

1.2-micron multi-section quantum dot superluminescent diodes
Superluminescent diodes (SLD) with a center wavelength of 1.2μm are of interest for use in medical imaging of skin tissue especially in the field of optical coherence tomography (OCT). In this thesis a ridge-waveguide multi-section quantum dot SLD that emits at 1.2μm with a bandwidth greater than …

Investigation of Narrowband Acousto-Optic Tunable Filters for Semiconductor Laser Tuning
… silica. The second source was constructed from a superluminescent diode with an Indium Phosphide (InP) active layer and produced >5 mW over 1650 – 1750 nm. This source was subsequently used for characterising a frequency shifting, quasi-collinear AOTF for its tuning relation, response to different …
