Bottom-up fabrication of lasers via epitaxial growth is emerging as a promising alternative to conventional top-down methods, offering the potential to realize micro-lasers with ultra-low optical losses. In this project, we aim to demonstrate electrically injected lasing in InP/InAsP multi-quantum well micro-ring cavities, grown using the selective area epitaxy technique. These on-chip microcavity lasers hold significant promise for a wide range of applications, including telecommunications, sensing, and as light sources in next-generation photonic integrated circuits.
