Quadrature Amplitude Modulated Microwave Signal Generation Using a Single Electro-Optic Nd:YVO $_{4}$ Solid-State Laser

In this communication a new optical scheme is described that is able to generate quadrature amplitude modulation RF signals, with exceptional flexibility and tunability. The device readily implements a channel-adaptive transmitter for wireless communications with multiple modulation formats and radio bands. Due to the optical generation, the transmitter is particularly ideal for radio over fiber applications.
