“Lumerical’s software has been invaluable to our research. Very useful features are being continuously added to maintain a market leading reputation.”
The University of Bristol and Lumerical have had a relationship since 2011, and have used FDTD modelling in numerous nanophotonic projects. Since 2015 Bristol have been using FDTD within the UK EPSRC project : Manufacturing of nano-engineered III-nitride semiconductors (www.manugan.org) led by the University of Bath along with the Universities of Sheffield and Strathclyde. 3D FDTD has been used in the analysis and design of micro and nanostructured GaN LEDs and lasers including nanorods, microdisks and nanotubes. Resonant wavelengths and 3D field distributions have been calculated which are very useful in understanding device behaviour and performing structure optimization.
The University of Bristol has had a relationship with Lumerical since 2011. With the use of FDTD, simulations have moved things forward significantly for the number of projects underway involving various partners.
- Origins of resonances within a single InGaN/GaN nanorod.
- Confinement enhancement in InGaN Microdisks.
- Origin of resonances in axial InGaN/GaN nanotube microcavities.
Further to this, we are developing other novel devices in GaN that can be used as sensitive detectors. This presentation highlights all these projects.
