III-V nanopillar optical links

We are combining the advantages of III-V nanopillars with silicon photonics platforms.

We will demonstrate electrically pumped high output power nanopillar array laser with high coupling efficiency and nanopillar photodiodes.

Using metal organic chemical vapour deposition (MOCVD) and molecular beam epitaxy (MBE) coupled with µ-photoluminescence amd Fourier transform infrared spectroscopy (FTIR) characterisation, we aim to show the potential of new platforms for III-V on silicon photonic devices through superior detectivity and ultra-low noise floor.

We expect technological breakthroughs in size, speed and energy efficiency. We hope fully-integrated optical links with silicon photonics and electronics will offer a solution to the limit on the number of interconnections between electronic devices such as multicore processors.
