We propose and experimentally demonstrate one novel scheme to improve the performance of the vector millimeter-wave (mm-wave) signal generated by intensity modulator based on optical carrier suppression. The phase distribution of the vector mm-wave signal after one square-law photodiode detection becomes nonuniform. We optimize the phase factor at the transmitter side and make the phase distribution...
We propose a novel and simple scheme for high-frequency photonic vector millimeter-wave (mm-wave) signal generation based on photonic frequency doubling enabled by a single directly modulated laser (DML), precoding, and analog frequency upconversion. The introduction of a DML avoids the need for an external optical modulator and, thus, simplifies the architecture and reduces the cost. The adoption...
