Abstract
This paper proposes a reconfigurable all-optical signal processing node architecture with selective all-optical signal processing in one simple configuration without optical-electrical-optical (O/E/O) conversion at the heterogeneous network connection node or repeater node. Proof-of concept experiments of encryption-key data superposition for binary phase shift keying and quadrature phase shift keying show the nonlinear optical effect generation within 1.5-dB and 3.5-dB characteristic degradation. Self-phase modulation and stimulated Brillouin scattering caused by increasing the highly nonlinear fiber input of pump light is the primary cause of signal degradation in the experiment.
