title = "Improving ASE-based Optoelectronic Oscillator Performance Using a Chirp-like Slicing Approach",
abstract = "The performance of an ASE-based optoelectronic oscillator (OEO) is enhanced through a chirp-like slicing approach. By spectrally slicing the amplified spontaneous emission (ASE) source using a chirp function, the in-band chirp within the pass-band of the microwave photonic (MWP) filter - induced by the fiber's third-order dispersion (TOD) - is effectively eliminated. When a 25 km fiber is incorporated, this technique achieves a more than 7-fold reduction in filter bandwidth, along with an amplitude enhancement of 9.3 dB. As a result, once the feedback loop is closed, the sidemode suppression ratio (SMSR) improves by 10.7 dB, the phase noise is reduced by 13 dB at a 4 kHz offset at 7.2 GHz, and the output power is increased by 11.7 dB.",
