TL;DR: A high-order photonic differentiator is proposed and experimentally demonstrated using on-chip complementary metal oxide semiconductor-compatible cascaded microring resonators, including first-, second-, and third-order differentiators.

TL;DR: It is shown that the output logic with dark return-to-zero (RZ) format has a large power penalty and the Q-factor is larger than 6 and the extinction ratio is largerthan 6.3 dB for all logic gates within 16 nm wavelength range.

TL;DR: A new cascaded microwave photonic filter that can realize a high Q value is presented, consisting of two infinite impulse response filters based on two active loops using cross-gain modulation of the amplified spontaneous emission spectrum of the semiconductor optical amplifier.

TL;DR: A novel wideband tunable optoelectronic oscillator based on a microwave photonic filter (MPF) with an ultra-narrow passband is proposed and experimentally demonstrated, the first time realizing such a narrow passband in single-passband MPF.

TL;DR: The proposed converter is capable of handling multiple wavelengths in wavelength division multiplexing (WDM) networks, enabling the conversions between WDM-PDM and W DM-MDM, which is promising to further increase the throughput at the network interface.
