Poling efficiency

Fig-2. Correlation of ionic conductivity with poling efficiency (second-order nonlinear optical activity). The upper graph shows conductivity measured as a function of temperature while the lower graph shows second-order nonlinear optical activity (measured by second harmonic generation, SHG) as a function of temperature. Note that second-order NLO activity starts to decrease with the onset of conductivity. Conductivity in this case was shown to arise from ionic impurities... [Pg.14]

The sum of the poling saturation limit values for different processes (P = Pi + P2 + P3) represents the overall poling efficiency under the experimental conditions temperature, geometry, poling field, atmosphere. [Pg.58]

To improve the thermal stability, a high-Eg cardo-type polyimide with a dendronized CLD-type chromophore has been developed [119]. A high poling efficiency was achieved to afford a very large EO coefficient (71 pm/V at 1.3 pm) more than 90% of this value can be retained at 85°C for more than 650h. [Pg.167]
