Abstract
Microwave bandpass modulators made using Mach-Zehnder interferometers in lithium niobate with periodic phase reversal electrodes have been developed for operation at 1.3 μm. These modulators are most useful in applications requiring electrooptic modulation at a single frequency or in a range of frequencies with less than an octave bandwidth. The performance of two experimental devices, with center frequencies of 10 and 21 GHz, will be described and compared with theory. The response of the 21-GHz modulator is higher at that frequency than the response of any baseband modulator in LiNbO3.
