Light-Emitting Diodes

We present the optical simulations of a novel illumination source based on nanoLED arrays for the possible application in superresolved microscopy. We are simulating the images of various gold nanoparticle arrangements collected by the proposed nanoillumination microscope. The images are then analysed in order to understand the capabilities and limitations of the microscope.

Deep ultraviolet (DUV) light emitting diodes (LED) made of Aluminium Gallium Nitride (AlGaN) are increasingly considered as light sources for medical as well as material processing applications. Recent research on AlGaN DUV LEDs focuses on the enhancement of the efficiency. The efficiency of AlGaN LEDs is limited by a low hole injection efficiency and TM-polarized […]

We introduce a rate equation based numerical model suitable for the description of the wide spectral asymmetry experimentally observed at the two facets of multi-electrode tapered superluminescent diode based on Quantum Dot material. Numerical simulations carried out with this model were able to quantitatively reproduce the behavior of a two-section SLD and explain the reported […]
