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 propose and investigate partially-degenerate four-wave mixing as an efficient and ultrahigh-bandwidth method for improving the microwave gain of analog fiber optic links. A flat 9-dB gain is experimentally demonstrated over an ultra-wideband of 14GHz.
