We characterize the modulation linearity of a silicon Mach–Zehnder modulator with a single-drive push–pull configuration. The 3-dB electro-optic bandwidths of the modulator are 15 and 32 GHz at 0 and 6 V reverse biases, respectively. The best spurious-free dynamic ranges (SFDRs) for the second-order harmonic distortion and the third-order intermodulation distortion are measured to be 97.7 dB·Hz2/3...
We propose and experimentally demonstrate a simple photonic approach to achieving tunable and reconfigurable bandpass microwave photonic filters (MPFs) based on cascaded microring resonators (CMRRs). The optical spectrum of the silicon CMRRs could offer two bandpass responses to separately filter the optical carrier and one of the sidebands generated by the phase modulation. Thus we could achieve...
