Ultra-Selective Flexible Add-Drop Multiplexer Using Rectangular Stimulated Brillouin Scattering Filters
Résumé
We demonstrate optical separation-aggregation of a ~2-GHz sub-band for a multi-band OFDM signal in QPSK and 16-QAM formats. The band gap is 300-MHz by using a rectangular optical filter based on stimulated Brillouin scattering.
