| description | An apparatus and method for generating a dense wavelength division and multiplexing (DWDM) optical stream in a photonic integrated circuit (PIC) is disclosed. An optical input source including a number (N) of optical channels (wavelengths) may be separated (de-interleaved) into multiple optical streams, each including a corresponding subset of the optical channels of the optical input source. Each of the multiple split optical streams may be modulated with an associated set of data streams by silicon-based micro-ring modulators to generate a corresponding modulated optical stream. A first pair of the modulated optical streams may be combined (interleaved) to generate a first optical output stream including N/2 modulated optical channels, and a second pair of the modulated optical streams may be combined (interleaved) to generate a second optical output stream including N/2 modulated optical channels. The channel spacing of the first and second optical output streams may be twice the channel spacing of the opt |
