Abstract: We propose a new modulation approach based on multi-phase coded signal (MPCS) to increase stimulated Brillouin scattering (SBS) threshold in high power narrow-linewidth fiber amplifiers. To investigate the SBS suppressing capacity of the proposed modulation… read more here.

Abstract: We propose a simple polarization-independent coherent detection scheme for cost-sensitive short to medium reach applications. The Alamouti-coded signal is generated in a dual-polarization transmitter and received by an electro-absorption modulated laser (EML) for arbitrary incoming… read more here.
