We should note that since stress is related to strain, birefringence effects could also be described in terms of strain-optical, or elastooptical, coefficients. Collectively, these are sometimes referred to as Pockets coefficients. 

Tables 4.4-3-4.4-21 are arranged according to piezoelectric classes in order of decreasing symmetry (see Table 4.4-2), and alphabetically within each class. They contain a number of columns placed on two pages, even and odd. The following properties are presented for each dielectric material density q, Mohs hardness, thermal conductivity k, static dielectric constant Sij, dissipation factor tanS at various temperatures and frequencies, elastic stiffness Cmn, elastic compliance s n (for isotropic and cubic materials only), piezoelectric strain tensor di , elastooptic tensor electrooptic coefficients r k (the lat-...

Broussoux and Mkheron [17] reported electrooptic and elastooptic effects in stretched PVDF. The linear EO coefficients in PVDF were measured at room temperature and constant stress at the He-Ne laser wavelength. The refractive indices n, 1.444. A = 1.436, and n, 1.42S and electrooptk coefficients rn = 0.10 pmA, 0.21 pm/V were OKasured. The secondary electrooptic effect estimated for the longitudinal configuration was ZS% of the measured free electrooptic coefficient. The quadratic electrooptic coefficients at constant strain and stress were gu 0.02 m /C and ga s 0.01 m /C. ...
