Abstract
Methods and devices are provided to facilitate production of optical signals that exhibit reduced crosstalk noise and intersymbol interference. In some configurations, a multi-stage optical interleaver, including a first and a second optical interleaver, is used to process a first and a second set of input optical channels. The composite optical output of the multi-stage interleaver includes the first set of optical channels and the second set of optical channels, where each of the first and second set of input optical channels is processed once by the first optical interleaver and once by the second optical interleaver. As such, the first and second sets of input optical channels are each filtered twice using only two optical interleavers.
