摘要：
Reflection, wavelength modulated reflection and transmission spectra at P, P (S, S) and 45 degrees, 45 degrees (135 degrees, 135 degrees) polarizations for incidence angles close to normal and Brewster one were researched in quantum In0.3Ga0.7As layers. Isotropic wavelengths lambda(0)-1.137 mu m (1.09 eV), lambda(02)-1.11 mu m (1.12 eV) and lambda(03)-0.932 mu m (1.09 eV) had been revealed. The refractive indexes n for P, P (S, S) and 45 degrees, 45 degrees (135 degrees, 135 degrees) polarizations are intersecting in these wavelengths and theirs differences Delta n = n(PP) - n(SS) (Delta n = n (45 degrees) - n (135 degrees)) intersects the null axis. The isotropic wavelength (lambda(0)) is shifted towards the long wavelength region at Brewster angle in reference to the case of perpendicular incidence of light (phi = 7 degrees) on the QW surface.
