英文摘要	Abstractthe in-plane optical anisotropy (ipoa) in inas/gasb superlattices has been studied by reflectance difference spectroscopy (rds) at different temperatures ranging from 80 to 300 k. we introduce alternate gaas- and insb-like interfaces (ifs), which cause the symmetry reduced from d2d to c2v. ipoa has been observed in the (001) plane along [110] and [11ˉ0] axes. rds measurement results show strong anisotropy resonance near critical point (cp) energies of inas and gasb. the energy positions show red shift and rds intensity decreases with the increasing temperature. for the superlattice sample with the thicker insb-like ifs, energy positions show red shift, and the spectra exhibit stronger ipoa. the excitonic effect is clearly observed by rds at low temperatures. it demonstrates that biaxial strain results in the shift of the cp energies and ipoa is enhanced by the further localization of the carriers in insb-like ifs.pacs78.67.pt, 78.66.fd, 78.40.fy
