•The light wave birefringence is observed in quantum wells (QW) In0.68Al0.1Ga0.13As/In0.42Al0.22Ga0.24As.•The anisotropy of optical functions of QW structure was revealed.•The interference in the QW layers indicates the presence of isotropic wavelength at 1.246 μm.•The effective masses of heavy and light holes were estimated.
The polarization dependences of reflection and wavelength modulated reflection spectra of quantum wells In0.68Al0.1Ga0.13As/In0.42Al0.22Ga0.24As were investigated. Spectral dependences of refractive indices, extinction coefficients, real and imaginary parts of dielectric constants of quantum wells structures for different polarizations were calculated by the Kramers–Kronig analysis. A phenomenon of birefringence and an interference of polarized light waves in quantum wells were researched. The isotropic wavelength λ0 = 1.246 μm was found out. Interference spectra changes the density of fringes and refractive indices (Δni, ΔnKK = nР,Р–nS,S) intersect zero axis at energy of isotropic wavelength (0.955 eV).
