摘要： In a radio frequency (RF)-photonic arbitrary waveform generator (AWG), an optical carrier signal is phase-modulated using an arbitrary waveform optical phase generator (AWPOG), which may include, e.g., sequential optical phase modulators. The phase-modulated optical signal is combined with a version of the optical carrier signal to yield an optical waveform, whose amplitude varies with a phase shift introduced by the AWPOG to the optical carrier signal. By manipulating electrical inputs to the AWPOG which control the phase shift, the optical waveform can be arbitrary shaped. The optical waveform may then be converted to an electrical waveform having a radio frequency.

摘要： According to one embodiment, a microwave photonic band-stop (MPBS) filter uses an electrical input signal to drive an optical Mach-Zehnder modulator. A modulated optical carrier produced by the modulator is applied to an optical filter having at least two tunable spectral attenuation bands that are located substantially symmetrically on either side of the carrier frequency. The resulting filtered optical signal is applied to an optical-to-electrical (O/E) converter to produce an electrical output signal.

摘要： A radiofrequency (rf) signal-processing device offers the possibility of high bandwidth operation. The disclosed device applies principles of microwave photonics and Linear Amplification based on Nonlinear Components (LINC). For some applications, the device may be embodied in an rf amplifier or rf transmitter. In an embodiment, an optical phase modulator is configured to receive an optical carrier signal as input, and further configured so that, when driven by an rf modulation signal, it will produce a complementary pair of optical signals as output. Each of a pair of detectors is configured to convert a respective one of the complementary optical signals to an rf signal. An rf combiner is configured to add the converted radiofrequency signals from the detectors to form an output signal.
