Abstract
A new approach to generate high-quality broadband frequency swept millimeter-wave (mm-wave) waveforms based on photonics-assisted frequency up conversion of a low-frequency chirped drive signal has been proposed. This is made possible by using an unbalanced temporal pulse shaping system involving two cascaded Mach-Zehnder modulators both biased at the minimum transmission points. The proposed approach is verified by simulations. A frequency swept mm-wave pulse with its instantaneous frequency spanning from 40 to 100 GHz and a chirp rate of 66.7 GHz/ns is generated thanks to 40 times frequency up conversion. Two-fold improvement on the time-bandwidth product of the generated waveform is also achieved thanks to the cascaded modulation scheme.
