About the Project
The newly established metal-organic chemical vapour deposition (MOCVD) capability at Cardiff University and the availability of molecular beam epitaxy (MBE) provides a complementary experimental setting for the study in this work. The project will concentrate on developing active device structures of 1.55 µm QD lasers with an aim to achieve superior optical properties and improved gain characteristics. Cross-examination using AFM and PL can correlate the growth parameters, morphology and optical quality of the quantum dots. QD development on native InP wafers will be carried out in parallel with the development of InP growth on mismatched Si substrates. Electrically injected lasers with temperature-insensitive and low threshold current operation will be demonstrated to guide material development and optimisation.
Start date: April, July or October 2021. 4 years Full Time.
