摘要：A Mach-Zehnder interferometer 200 comprising an optical splitter 201 having at least one input 203R and at least two outputs 204L . 2048, an optical recombiner 202 having at least two inputs 205L .205R and at least one output 2068 and a pair of interferometer arms 207L 2078. Each of the arms couples an output of the splitter to an input of the recombiner. The arms are configured such that each of the outputs of the splitter is coupled to an opposite side input of the recombiner so as to compensate for phase imbalance of light propagating through the arms. The interferometer is configured such that the splitter and the recombiner operate in cross-state to compensate for split ratio offset errors in the splitter and recombiner.
