Phase-locked two-dimensional arrays of implant isolated vertical cavity surface emitting lasers

The fabrication and characterisation of two-dimensional phase-locked arrays of vertical cavity surface emitting lasers is reported. The three two-dimensional array structures characterised were a 2 × 3 periodic array of 10μm2 lasers, a hexagonal array and a centred hexagonal array of 5 μm hexagonal lasers. All arrays were fabricated using the same technique which was a combination of mesa etching and oxygen implantation isolation.
