Fabrication and Experimental Demonstration of a Four-Channel $,\times,$ 40 Gb/s TriPleX All-Optical Wavelength Conversion Platform

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 Si₃N₄-SiO₂ microring resonators, delay interferometers and heating elements. The total footprint of each array is 2.19 mm² and the power consumption per integrated heater is below 80 mW. We have interconnected the TriPleX chip with SOAs and we demonstrate experimentally 4 × 40 Gb/s, parallel and wavelength tunable wavelength conversion with power penalties of less than 3 dB.
