We demonstrated the superluminal propagation at negative group velocity using stimulated Brillouin scattering (SBS) in optical fibers. In the scheme, the Stokes wave is circulated back into the ring cavity for Brillouin lasing to enhance the peak loss. The experiment demonstrated the superluminal light propagation can be realized by increasing the input signal power. The largest time advancement of 221.2ns has been observed. Correspondingly, the negative group velocity is -0.15c and the group index is -6.636.
We present a polarization-diversity coherent receiver that enables wavelength-multiplexed reception without arrayed waveguide gratings. We compensate in-phase and quadrature imbalance using a MIMO equalizer, enabling ...

We propose and experimentally demonstrate a simple and cost-effective scheme to converge a 60-GHz radio-over-fiber (RoF) system with a wavelength division multiplexed-passive opticalnetwork (WDN-PON) system. Only 10-GHz electronic devices are used to generate a 60-GHz RoF signal based on frequency-sextupling technology. For n-channel WDN-PON and RoF converged system, only n+1 modulators are required.
A polarization splitter rotator (PSR) is a highly promising solution for polarization management in photonic integrated circuits (PICs). This paper proposes a PSR structure design based on AlGaAs-on-insulator (AlGaAsO...

In this letter, two kinds of continuous wavelength-tunable light sources are achieved and investigated experimentally using a self-seeding reflective semiconductor optical amplifier （RSOA）. Over 40 single mode wavelengths with 100 GHz spacing are generated by setting the parameters of the wavelength selective switch. The peak power of each wavelength reaches over 0.2 dBm with the signal-to-noise ratio （SNR） 〉 35 dB. The proposed schemes are appropriate for multi-wavelength-tunable light sources; the maximum number of wavelengths generated can reach to 4.
