We experimentally demonstrate an all-optical architecture for the linearization of a phase-modulated interferometrically detected microwave photonic link. We couple off a small part of the phase-modulated signal and combine it with a pump lightwave to produce a comb of idlers in a cascaded four-wave mixing process. The phase-matching requirement of the cascaded process ensures that integer multiples...
We present a high SFDR (123.7 dB) phase-modulated optical link, designed using nonlinear optical processing to eliminate third-order distortion. We also show its application to other areas of microwave photonics, specifically programmable function generation.
We demonstrate a microwave function generator based on precisely engineering the distortion in a microwave photonic link. By distorting a 5-GHz sinusoid we are able to generate a 5-GHz triangle wave and square pulse train.
We present all-optical distortion cancellation in phase-modulated analog-photonic links by combining the phase-encoded signal with lines from an optical comb generated from signal. Experimentally, we fully cancel third-order distortion increasing the link SFDR by >8.3dB.
