We present a scalable circuit that performs multichannel, all-optical wavelength conversion employing semiconductor optical amplifiers (SOAs) and a densely integrated TriPleX photonic chip. The TriPleX device performs chirp filtering and signal polarity inversion with on-chip signal processing. The chip includes a total number of 40 arrays of Si3 N4–SiO2 microring resonators, delay interferometers and heating elements. The total footprint of each array is 2.19mm2 and the power consumption per integrated heater is below 80 mW. We have interconnected
the TriPleX chip with SOAs and we demonstrate experimentally 4x40 Gb/s, parallel and wavelength tunable wavelength conversion with power penalties of less than 3 dB.
