41) gives the relation 2 1 y2 2 1 ¼1 À r E þ Z þ r E þ 41 41 n20 n20 n20 ð1:44Þ which means that the refractive indexes along the new axes , Z, and y are: 1 n ¼ n0 þ n30 r41 E 2 1 nZ ¼ n0 À n30 r41 E 2 ny ¼ n 0 ð1:45Þ ð1:46Þ ð1:47Þ for n0 ) n30 r41 E=2. 7. 16 ELECTRO-OPTIC EFFECT Exercise: Following the mathematical development above, show that for an electric field E along the axis [001] the principal axes of the index ellipsoid are directed along x, y, and z with the index ellipsoid having the form 1 1 z2 x2 2 þ r63 E þ y2 2 À r63 E þ 2 ¼ 1 ð1:48Þ n0 n0 n0 thus meaning that, in the input crystal plane (110) that is also the x-z plane, the index of refraction changes only along x and is constant along z.
Photochromic effect and the Band-transport model. On the left side we are representing deep photoactive centers (acceptors and donors) and shallower centers close to þ . In this figure electron acceptors, the CB, with empty donors (acceptors) only, labelled ND2 both for deep and for shallow centers, are represented as positively charged so that a non photoactive negative ion should be close to these charged acceptors to ensure local electric neutrality. On the right side we see that under the action of light (represented by the arrows), the electrons are excited into the conduction band.
3 PHOTOCHROMIC EFFECT As already pointed out above, photochromic effects are not expected for the onecenter model. Let us therefore refer to the two-center model including shallow traps. 35) and is a function of the irradiance I. Photochromic effects are easy to measure and may give valuable information to be compared with that obtained from photoconductivity. 23) and find the stationary equilibrium (that is the null time derivative) for ND2 þ þ which is only possible if we are far from the extremes ND2 ¼ ND2 or ND2 ¼ 0.
