    • -1. From these Pij coefficients and from the stiffness parameters of GaAs, we deduce the photoelastic coefficient as dn/dη= P11 C12 + P12 C11 + P12 C12 2n (Ref.) and d kd2 /dη= 2π λ2 dn/dη, where λ2 is the probe wavelength. It is to be mentionned that close to 390 nm there is an efficient optical interband transition (Ref.). As a consequence, the imaginary part of the refractive index is large and similar to the real part. Moreover, due to a huge energy dependence of the optical refractive index, the photoelastic coefficients exhibit large values in the vicinity of this interband transition
