Abstract Arrays of GaAs pyramids with square (001) bases of length 1{endash}5 {mu}m have been fabricated by molecular beam epitaxy regrowth on pre-patterned GaAs (001) substrates. The optical properties of the pyramid faces have been studied by microreflection and microtransmission imaging measurements with light ({lambda}=900{endash}1000nm) incident through the pyramid base. Digitized charge coupled device images indicate that total internal reflection occurs at the {l_brace}110{r_brace} pyramid facets and that their reflectivities are greater than 80%, provided overgrowth of the facets does not occur. These properties suggest that such structures may be suitable as the top mirror in novel micron-scale vertical microcavity devices. {copyright} 2001 American Institute of Physics.
