Electromagnetic simulations of the nanoLED array for the ChipScope microscope

University of Rome Tor Vergata has performed electromagnetic simulations of the nanoLED array for the ChipScope microscope. In this first year, special attention has been given to the qualitative behavior of visible light emission and propagation in arrays of nano-emitters in different device layouts and dimensions.

The first generation of ChipScopenanoLEDs with pixel dimensions in the order of micrometers have been studied by a ray tracing approach, using COMSOL Multiphysics software, while light emission from devices as targeted for the end of the project have been studied by finite difference time domain (FDTD) method, using CST EM simulation software. The simulation results will be used to optimize the nanoLEDs produced at Technical University of Braunschweig, and to develop the image reconstruction algorithms that will be implemented at Ymaging.
