“…If low-frequency RF phase fluctuations are not acceptable, then the interferometer needs stabilization. This can be achieved using a piezo controller inside the interferometer, similar to the stabilization of the fiber-based interferometer used for RF arbitrary waveform generation in [49], or through integration.…”

Abstract-We demonstrate a rapidly frequency-tunable radio frequency (RF) filter using microwave photonics technology for ultrawideband RF spread spectrum applications. A pair of electro-optic frequency combs is arranged as a dispersive tapped delay line in a differential detection configuration to implement a programmable finite impulse response RF filter. Our photonic scheme enables both fast frequency tuning on the order of tens of nanoseconds and wide tuning range (>7.5 GHz) with minimal variation of RF gain and passband shape. The low control voltage (ca. 1 V) and the linear relationship between control voltage and passband frequency facilitate agile frequency tuning for processing of signals with time-varying frequency content, while differential detection increases the photocurrent by a factor of two and suppresses common mode intensity noise. We exploit the rapid tunability of the implemented filter to demonstrate dynamic tracking of frequency-hopped and chirped RF signals. An experiment that performs dynamic filtering of an input chirp signal (3.92-GHz center frequency, up-chirped by >2 GHz within 100 ns) obscured by strong broadband noise achieves ∼11-dB signal-to-noise ratio (SNR) improvement. The SNR obtained is in addition to that available from standard matched filtering or pulse compression processing, suggesting strong potential for enhanced resistance against broadband noise jamming.

“…As mentioned in Section 2, one of several approaches for photonic generation of arbitrary waveforms is Fourier Transform Pulse Shaping (FTPS) following by Frequency to Time Mapping (FTM) [12,22,23,29]. This approach exploits the broadband feature of photonics and its inherent large Time Bandwidth Product (TBWP).…”

“…4 such that a delay mismatched optical interferometer is added around the FTPS to form oscillations corresponding to the center frequency of the bandpass waveform and thus allows the FTPS to dedicate its entire resource to shape the waveform complex envelop [29]. Further explanation and results for this improved implementation is given in the caption of Demonstration of time aperture expansion by pseudo-noise modulation of the optical pulse train through the generation of a microwave Costas sequence -Time domain measurement of the W-band Costas sequence with a 10 GHz center frequency and a 1 GHz frequency step [29] (all figures and results are courtesy of and adapted from A. Weiner).…”

“…Fig. 6 presents a practical demonstration of a 15-times aperture expansion using a pseudo-noise switching to generate a W-band Costas sequence of length 15 [29]. With this technique, it is possible to extend the time limited waveform to an almost arbitrary time length which is necessary for high resolution radar and ranging applications.…”

This paper reviews recent progresses on optical arbitrary waveform generation (AWG) techniques, which could be used to break the speed and bandwidth bottlenecks of electronics technologies for waveform generation. The main enabling techniques for optically generating optical and microwave waveforms are introduced and reviewed in this paper, such as wavelength-to-time mapping techniques, space-to-time mapping techniques, temporal pulse shaping (TPS) system, optoelectronics oscillator (OEO), programmable optical filters, optical differentiator and integrator and versatile electro-optic modulation implementations. The main advantages and challenges of these optical AWG techniques are also discussed.
