A detailed study of a two-dimensional (2D) lattice laser was carried out. The devices used were InGaAsP-InP stripe lasers consisting of seven 0.8% compressively strained quantum wells. A 2D hexagonal array of holes was etched through the top contact over a 50μm length using focused ion beam (FIB) etching. Purely single mode operation was maintained over the entire operating current range upto over 3.5 times threshold. A transverse coupling of the optical mode took place over a very short distance in the etched region despite the 2D grating being placed outside the ridge waveguide.
