TL;DR: In this paper, a high-resolution tunable RF/microwave photonic notch filter with low-noise performance is presented based on using a dual-input electro-optic intensity modulator together with a frequency-shifting amplified recirculating delay line loop.

TL;DR: In this paper, a high-resolution low-noise single-laser photonic filter that can operate to high frequencies is presented, based on the single-sideband suppressed carrier electro-optic modulator frequency shifter that enables high frequency shifts to be realized in a frequency shifting amplified recirculating delay line loop structure.

TL;DR: In this paper, a new photonic method was used to generate the sawtooth waveform in a serrodyne optical frequency translator, which has wideband capability for realising higher optical frequency shifts and sideband suppression than electronic approaches.

TL;DR: In this article, the authors theoretically and experimentally investigate the high-resolution performance of an optical microresonator-based sensor scheme incorporating microwave photonic sidebands processing, where optical power and phase profiles of the modulation sidebands are equalised to achieve ultrahigh-rejection RF notches with ultranarrow tip width in the electrical spectrum.

TL;DR: In this article, a spectrum-sliced microwave photonic filter exhibiting multitap characteristics, high-frequency operation, and insensitivity to the operating optical wavelength is presented, based on an amplitude-modulated single sliced source and a novel sinusoidal group delay line structure, integrating tap weights and delays in one unit.
