Phase-Locked Two-Dimensional Arrays of Vertical Cavity Surface Emitting Lasers

We report the characteristics of two-dimensional phase-locked arrays of vertical cavity surface emitting lasers. Three different two-dimensional array structures have been realized, they are a 2×3 periodic array of 10 µm squares, a hexagonal array and a centered hexagonal array of 5 µm hexagons. All arrays were fabricated using the same technique which was a combination of mesa etching and oxygen implantation isolation. The threshold current of 2×3 periodic array was 24 mA, hexagonal array was 30 mA and centered hexagonal array was 22 mA. The far field beam angle was about 2°. The centered hexagonal array has the most circularly symmetric far field beam pattern.
