Abstract
The performance of impedance-matched lumped-element and traveling-wave integrated-optical phase modulators is compared. This analysis shows that the performance of lumped-element modulators in LiNbO/sub 3/ exceeds that of traveling-wave devices when the product of the modulation frequency and electrode length is less than approximately 20 GHz-mm. Impedance-matched lumped-element modulators are particularly applicable to narrow band systems operating up to several gigahertz.<>
