Abstract
Systems and methods are provided for modulating, channels in dense wavelength division multiplexing ('DWDM') systems. In one aspect, a modulation and wavelength division multiplexing system includes a channel source and a waveguide tree structure disposed on a substrate. The tree structure includes waveguides branching from a root waveguide. The waveguides include two or more terminus waveguides coupled to the channel source. The system also includes one or more modulator arrays disposed on the substrate. Each modulator array is optically coupled to one of the two or more terminus waveguides and is configured to modulate channels injected into a terminus waveguide from the channel source to produce corresponding optical signals that propagate from the terminus waveguide along one or more of the waveguides to the root waveguide.
