We report a new type of electrooptic deflector using lens effect which is able to scan a space in two dimensions. The proposed device was developed from a quasi-velocity-matched electrooptic phase modulator with periodic domain inversion, therefore, it can operate efficiently at a microwave frequency. In the experiments, the demonstration of its operation and applications to ultrafast light control was done at 16.25 GHz.

We demonstrate an electrooptic synthesis technique for generating arbitrarily shaped short optical pulses from a CW narrow linewidth laser. For the optical pulse shaping, a large-amplitude electrooptic phase modulator is specially fabricated by employing the quasi-velocity-matching. The phase modulated light having sidebands as wide as 1 THz is separated and phase-only-controlled spatially by a liquid crystal modulator array. After composing the light by using a grating, nearly 1. 2 ps of Fourier-transform-limited optical pulses is obtained.
