We present a compound photonic amplification-based cross-port wavelength converter utilizing the self-polarization switching (SPS) effect of a Traveling Wave semiconductor optical amplifier (TWSOA). This paper mainly focuses on achieving higher conversion efficiency (CE) with faster response time by removing the SOA’s sensitivity to the polarization that affects switching output. For this purpose, an Erbium-doped fiber amplifier is parallelly incorporated in Mach Zenhderic configuration, and a comparative investigation of the Poincaré sphere points has been performed. The CE of −27.98 dB has been achieved and is also monitored with port-spacing and injection current. The optimized results of a Bit Error Rate of 10 –28 , a latency of 0.124277 ns, and the Optical Signal-to-Noise Ratio (OSNR) of 33.9 dB at 10 Gbps prove its excellency when compared with existing basic SOA-based converters.
