Fig. 4. Comparison of micro-structured modulator performance to prior designs and predictions on high frequency performances. (a) Measured voltage–bandwidth (1 dB) performance comparison of legacy LN ($0.3\;{\rm{dB}}\;{\rm{c}}{{\rm{m}}^{- 1}}\;{\rm{GH}}{{\rm{z}}^{- 1/2}}$, $15\;{\rm{V}} \cdot {\rm{cm}}$), thin-film regular LN ($0.69\;{\rm{c}}{{\rm{m}}^{- 1}}\;{\rm{GH}}{{\rm{z}}^{- 1/2}}$, $2.1\;{\rm{V}} \cdot {\rm{cm}}$), and thin-film segmented LN modulators ($0.26\;{\rm{c}}{{\rm{m}}^{- 1}}\;{\rm{GH}}{{\rm{z}}^{- 1/2}}$, $2.3\;{\rm{V}} \cdot {\rm{cm}}$). The shaded areas correspond to improved design space with other substrates. (b) Predicted performances of 20 mm long electrode for regular and segmented design up to 200 GHz bandwidth. Material legends indicate the substrate handle. (c) Velocity matching tolerances of segmented modulator with two different lengths. Curves represent EO bandwidth.
