1. An apparatus, comprising:
a laser comprising a waveguide, the waveguide having a variable width from a first end to a second end, the laser to generate optical energy of a plurality of lasing wavelengths;
a plurality of modulators, each of the plurality of modulators to modulate one of the plurality of lasing wavelengths with data; and
a semiconductor optical amplifier coupled to the plurality of modulators to amplify the modulated plurality of lasing wavelengths.
