Abstract:
1. A network device, comprising: a substrate; a plurality of optical sources provided on the substrate, each of the plurality of optical sources supplying a corresponding one of a first plurality of optical signals, each of the first plurality of optical signals having a corresponding one of a first plurality of wavelengths, the first plurality of wavelengths conforming to a first channel grid, each of the first plurality of optical signals having a predetermined optical parameter value, each of the plurality of optical sources further being configured to output a second plurality of optical signals, each of which having a corresponding one of a second plurality of wavelengths, the second plurality of wavelengths conforming to a second channel grid that is spectrally shifted relative to the first wavelength grid; a plurality of optical elements provided on the substrate, each of the plurality of optical elements providing an optical wavelength modulated with a data; a plurality of tuning elements, each of which being configured to modify a property associated with a corresponding one of the plurality of optical elements, such that, when the plurality of optical sources supplies the second plurality of optical signals, each of the second plurality of optical signals has the predetermined optical parameter value.
