Abstract
An integrated transmitter chip having a transmitter block, the transmitter block having: a first power divider optically connected to a first input port; a second power divider optically connected to a second input port; a first plurality of optical channels optically branched from the first power divider; a second plurality of optical channels optically branched from the second power divider; a first multiplexer optically connected to a first optical channel of the first plurality of optical channels and a first optical channel of the second plurality of optical channels, and a second multiplexer optically connected to a second optical channel of the first plurality of optical channels and a second optical channel of the second plurality of optical channels. The integrated transmitter chip may be configured to utilize polarization division multiplexing or wavelength division multiplexing to combine optical signals depending on the application of the corresponding integrated transmitter chip.
