3 pages, 4 figures, 1 table.-- PACS: 78.66.Fd;\ud78.20.Hp; 78.20.-eIn-plane optical anisotropies of (001)-oriented InAs/InP self-assembled quantum wires and dots structures are studied by means of photoreflectance in the spectral region of the E1 transition of bulk InAs. The energy position of the transition observed in the quantum wires depends on the light polarization; quantum dots do not exhibit, in contrast, such an optical anisotropy. This anisotropy is attributed to the splitting of the four-fold degenerate E1 transition produced by the strong triaxial behavior of the strain that appears in wires and not in dots.This work has received financial support by the Spanish\udCICYT under Grant Nos. MAT95-0966-C02-01 and TIC-\ud1020-C02-01.Peer reviewe
