The Modulation Index Optimization of Microwave Photonic Frequency Conversion Using Double-Sideband Suppressed-Carrier and Balance Detection

Abstract:

In this paper, on basis of DPMZM (Dual-Parallel Mach-Zehnder Modulator), an approach for microwave photonic frequency conversion using DSSC(double-sideband suppressed-carrier) and balance detection is demonstrated. DSSC and balance detection were used to realize high harmonic suppression, and achieve frequency conversion signal with high power and high spectrum purity. In addition, theoretical analysis and simulation results show that the optimal modulation index is m1=2, m2=1.81, and the harmonic suppression is greater than 30dB.
