(a) Schematic diagram of a periodically domain-engineered traveling-wave EOD; (b) designed shape of the domain-inverted region shaded for one elemental section; (c) schematic showing Fourier transformation of the deflected light beam.
Relation between parameters and . is the resolvable spot number for the rectangular beam profile. is the resolvable spot number for the Gaussian beam profile with a slit (width of ) placed just after the EOD.
Typical streak image of the deflected beam trajectory.
Relation between the maximum modulation index and the resolvable spot number for the Gaussian beam profile with the slit. The solid line indicates calculation. The open circles are obtained by the measurements.
