Abstract
An integrated transmitter chip comprising: at least one input port disposed at a first end; a first variable power divider optically connected to a first input port of the at least one input port, the first variable power divider being tunable to a first splitting ratio; a second and a third variable power dividers each optically connected to the first variable power divider, the second and the third variable power dividers being tunable to a second and a third splitting ratios; and a first and a second optical channels being optically branched from the second variable power divider, and a third and a fourth optical channels being optically branched from the third variable power divider; wherein an optical signal being launched into the first input port and having an input power is caused to be split by the first variable power divider into a first and a second optical signals.
