Photonic Generation of Millimeter-Wave Signals With Tunable Phase Shift
A novel photonic approach Protein Snacks to generating a frequency-quadrupled millimeter-wave (mm-wave) signal with a tunable phase shift is proposed and demonstrated.Two second-order optical sidebands are generated by using a Mach-Zehnder modulator (MZM) that is biased at the maximum transmission point and an optical notch filter.A polarization-ma
