Abstract

The use of a two-dimensional (2D) high-index-contrast grating (HCG) with square periodic lattice is proposed to realize surface-emitting lasers. This is possible because the use of 2D HCG, in which multiple resonant leaky modes are excited by the 2 orthogonal directions of the grating, causes the high reflective zone to be split into two regions. Hence, a dip of the reflectivity is formed to support the excitation of a resonant cavity-mode inside the 2D HCG. With suitable design on the dimensions of the 2D HCGs, Q factor as high as 1032 can be achieved.
