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 Si

microring resonators, delay interferometers and heating elements. The total footprint of each array is 2.19 mm

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.
