In this talk, we review some progresses on tunable fractional photonic differentiator and first-order linear ordinary differential equation solver with an electronically tuned microring resonator.
We have proposed an optically tunable optoelectronic oscillator (OEO) incorporating a single passband microwave photonic filter (MPF) based on an electro-optic phase modulator and a Fabry-Pérot semiconductor optical amplifier (FP-SOA). By replacing the electrical bandpass filter in a traditional single-loop OEO with the MPF, the oscillating frequency can be simply tuned by altering the bias current...
An all-optical UWB pulses generation and modulation scheme using cross phase modulation (XPM) effect of semiconductor optical amplifier (SOA) and DWDM-based multi-channel frequency discrimination is proposed and demonstrated, which has potential application in multiuser UWB-Over-Fiber communication systems.
Photonic generation of ultrawideband monocycle pulses is experimentally demonstrated by using a cascaded semiconductor optical amplifier and electroabsorption modulator. The polarity and the shape of the ultrawideband monocycle pulses can be electrically controlled and optimized.
We experimentally demonstrate all-optical 40 Gbit/s multicasting XOR logic gate for NRZ-DPSK signals by using non-degenerate four-wave mixing (FWM) in a highly linear fiber (HNLF). Triple-channel XOR outputs are simultaneously achieved in the experiment.
By introducing laser oscillation in erbium-doped fiber amplifiers, four-wave mixing effect is successfully suppressed and improvement of the amplifier performance is achieved. Explanations for the influence of lasing wavelength and optical power on the generation of four-wave mixing are presented. The results imply that this suggested approach can be applied in the practical dense wavelength-division...
