Abstract
An integrated transmitter chip comprising: at least one input port disposed at a first end of the integrated transmitter chip; a first variable power divider optically connected to each input port of the at least one input port; a second and a third variable power dividers optically branched from each first variable power divider; a first and a second optical channel optically branched from the second variable power divider, a third and a fourth optical channel optically branched from the third variable power divider; and at least one WDM optically attached to corresponding optical channels and configured to selectively modify the polarization of and multiplex corresponding optical signals into a output optical signal, wherein a laser beam is launched into an input port, split by corresponding variable power dividers based upon each dividers corresponding splitting ratio, then multiplexed and combined into an output optical signal having dual polarization modes.
