Abstract Nowadays high-frequency microwave signals are widely used in electronic warfare, radars and next-generation communication systems. It is difficult to break through the “electronics bottleneck” to generate high-frequency microwave signals by using traditional electrical techniques. With the development of microwave photonics, it is possible to generate stable and tunable microwave signalswith high frequencies. This thesiswill focus on millimeter/micro wave signal generation based on external modulators.

The working principle and modulation characteristics of Mach-Zehnder modulators (MZM) are introduced. Literature review is presented ongenerating millimeter/micro wave signals with 4-, 6-, and 8-times frequency multiplication based on cascaded MZMs or dual-parallel MZMs (DPMZMs). A novel scheme to optically generate a microwave signal with 10-times frequency multiplication is proposed. The proposed scheme is based on two DPMZMs and a polarizer. It does not require electrical phase shifters with specified degrees, which are needed in the conventional 10 times frequency multiplication structure. Simulation is conducted to evaluate the performance of the proposed scheme. When a 1 GHz RF drive signal turns into two DPMZMs with a 35dB extinction ratio, the proposed 10-times frequency multiplier with an optical sideband suppression ratio (OSSR) higher than 25 dB can be obtained. A 10 GHz mm-wave with an RF spurious suppression ratio (RFSSR) over 16 dB is generated. A frequency quadrupling scheme based on a DPMZM is experimentally demonstrated. With a 3 GHz RF drive signal, an OSSR higher than 8 dB is obtained and a 12 GHz mm-wave is generated with an RFSSR over 10dB.
