We have investigated the possibility of InP-based 2-dimensional (2D) photonic crystal experimentally and theoretically. To fabricate such crystal, we aimed at utilizing triangular rods and holes automatically formed at the surface of (111)A InP substrate by an anodization method. Favorable characteristics are that the rods and holes orient perpendicular to the surface and have submicron width and high aspect ratio. In addition, observed photoluminescence spectra indicated negligibly slow surface recombination at the anodized surface. From the calculation of band diagram, the photonic gap was found for uniform triangular rods. Thus low-damage 2D photonic crystal which controls light emission and propagation in the 2D plane can be realized by controlling the size uniformity and position of rods using the patterned oxide mask. |
