Paper Abstract

Silicon-based integrated microwave photonics presents an interesting platform for broadband microwave applications, offering high-speed modulation and a broad selection of devices. We propose and experimentally demonstrate an effective Mach-Zehnder modulator design to generate frequency-multiplied microwave signals. Using a continuous-wave laser signal modulated by an external microwave signal, we demonstrate that by filtering two non-adjacent frequency comb lines, the detected frequency-doubled signal can be improved considerably by suppressing the carrier frequency and unwanted side-band contributions. The demonstrated designs use a 12-GHz and a 21-GHz external driving signal to generate respectively a 24-GHz and a 42-GHz frequency doubled MW signals.
