Bidirectional Data Injection Operation of Hybrid Integrated SOA–MZI All-Optical Wavelength Converter

We propose a new and potentially integrable scheme for the realization of an all-optical binary full adder employing two XOR gates, two AND gates, and one OR gate. The XOR gate is realized using a Mach-Zehnder interferometer (MZI) based on a semiconductor optical amplifier (SOA). The AND and OR gates are based on the nonlinear properties of a semiconductor optical amplifier. The proposed scheme is driven by two input data streams and a carry bit from the previous less-significant bit order position. In our proposed design, we achieve extinction ratios for Sum and Carry output signals of 10 dB and 12 dB respectively. Successful operation of the system is demonstrated at 10 Gb/s with return-to-zero modulated signals.

This paper demonstrates a 10 Gb/s one-to-two-wavelength conversion configuration based on cross-gain modulation for optical access networks using a single TW-SOA. The method is capable of converting a signal data of specific wavelength 1541 nm to certain wavelengths of CW's laser 1554 nm and 1558 nm with 4 nm spacing. The pump power level was classified due to channel response. A result obtained was the best power level offering wavelength converter between −6 and 3 dBm. The conversion efficiency achievement provided an acceptable result for probe signals. The findings of -factor performance were investigated. The values were found to be more than 9 for point to point transmission and 20 km fiber configurations for the original and converted signal. The technique implemented at 20 km and the power of all channels were adequate to provide a splitting ratio of 1/64 for the launched pump power 3 dBm.

“…The standard approach to SOA-MZI-based WC of NRZ signals employs a single control (CTR) signal offering reduced complexity but enhanced susceptibility to pulse broadening and patterning effects due to the unbalanced gain saturation in the two SOAs [4]. These effects are partially compensated in the bidirectional push-pull scheme, which employs two control pulses travelling in opposite directions through the two MZI branches [4].…”

“…These effects are partially compensated in the bidirectional push-pull scheme, which employs two control pulses travelling in opposite directions through the two MZI branches [4]. The two control signals cause the same gain modulation to the two SOAs but induce a differential phase shift to the continuous-wave (CW) input signal components.…”

Abstract-We present a novel scheme for all-optical nonreturn-to-zero (NRZ) wavelength conversion with enhanced 2R regenerative characteristics. It employs a hybridly integrated semiconductor optical amplifier Mach-Zehnder interferometer using bidirectional data injection and an additional external continuous-wave signal for differentially biasing the interferometer arms, optimizing gain and phase conditions during the switching functionality. Experimental verification of its superior 2R regenerative capabilities are demonstrated for 10-Gb/s NRZ data signals.Index Terms-Integrated Mach-Zehnder interferometer (MZI), optical regeneration, optical signal processing, semiconductor optical amplifier (SOA), wavelength conversion (WC).
