Abstract :
Summary form only given. Semiconductor electrooptic modulators (EOMs) have drawn a significant attention for their large modulation bandwidth and low chirping. One drawback of such devices, however, is a large switching voltage mainly due to the weak linear electrooptic (LEO) effect. In this paper, we report an efficient semiconductor EOM with a switching voltage smaller than 1 V/mm. The rib waveguide phase modulator was fabricated on [100] GaAs/AlGaAs double hetero-structure p-i-n substrate.
