The low-temperature birefringence of spontaneously ordered GaInP is studied by using polarized transmission spectroscopy at 5 K. Refractive indexes no, ne and the birefringence Δnoe = no - ne are obtained by applying two independent techniques: (1) measuring the polarized transmission spectra with polarization parallel to each of the two cleaved edges individually; and (2) measuring one transmission spectrum with a cross-polarization configuration. The results of these two techniques are consistent, and both give Δnoe, ∼ 0.02 near the band-gap of partially ordered GaInP. Exact and approximate formulae have been derived for analyzing the cross-polarization spectrum. A possible device-polarization rotator-is proposed based on the in-plane birefringence.
