Abstract :
Summary form only given. The electrooptic lens (EOL) is an electrooptic phase modulator that provides quadratic spatial phase shift, therefore its focal length is controllable by changing the applied electric field. In principle, since the minimum focal length of EOL is reciprocal proportional to the modulation index, high modulation index is required for efficient lens effect. In this paper we propose the quasi-velocity-matched EOL with periodic domain inversion for ultrahigh-speed operation over 10 GHz.
