In this paper, we present the generation of high peak-power picosecond optical pulses in the 1.26 μm spectral band from a repetition-rate-tunable quantum-dot external-cavity passively mode-locked laser (QD-ECMLL), amplified by a tapered quantum-dot semiconductor optical amplifier (QD-SOA). The laser emission wavelength was controlled through a chirped volume Bragg grating which was used as an e...

Two schemes for polarization-insensitive optical spectral inversion without frequency shift based on four-wave mixing are proposed, both utilizing a conventional semiconductor optical amplifier (SOA) and two pump waves. The significant advantages of the configurations include their simplicity, effective suppression of the signal and one of the pump waves and a reduction in the noise associated ...

We propose a flat-top bandpass microwave photonic filter (MPF) with flexible tunability of the bandwidth and center frequency based on optical nonlinearities in a Fabry-Pérot semiconductor optical amplifier (FP-SOA). Phase-inverted modulation induced by cross-gain modulation (XGM) and optical spectral broadening induced by self-phase modulation (SPM) are exploited to achieve flat-top and bandwi...

We evaluated the energy efficiency per 1-bit transmission of an optical light source on InP substrate to achieve interconnection. A semiconductor amplifier (SOA) assisted extended reach EADFB laser (AXEL) was utilized as enhance compared conventional electro-absorption modulator integrated with a DFB (EML). The AXEL has frequency bandwidth extendibility for operation over 100 Gbit/s, which is d...
