Ultrawideband Impulse Radio Signal Generation Using a High-Speed Electrooptic Phase Modulator and a Fiber-Bragg-Grating-Based Frequency Discriminator We propose a novel approach to generating ...

We demonstrate novel phase-coded microwave signal generation based on a two-segment single-drive push-pull silicon Mach-Zehnder modulator. The coding signal and the microwave frequency are each ...

The three key factors limiting the bandwidth of the modulator are: (1) impedance matching; (2) microwave loss, primarily absorbed by the traveling waveguide and the silicon substrate; and (3) matching ...
