Abstract: A system is configured to determine a first power level of a first signal output from a first modulator, and determine a second power level of a second signal output from a second modulator. The first signal may include a first optical signal associated with a particular polarization orientation, and the second signal may include a second optical signal associated with the particular polarization orientation. The system is configured to determine a relationship between the first power level and the second power level, and to set, based on the relationship between the first power level and the second power level, a reverse bias voltage associated with the first modulator, where the reverse bias voltage may be used to control the first power level of the first signal.

Abstract: An optical device may include a transmitter to provide an optical signal via a set of channels and a modulator. The optical device may include two or more tributary modulators to modulate the set of channels with a training pattern. The optical device may include a set of optics to alter a first channel relative to a second channel of the set of channels. The optical device may include a detector to determine an optical power measurement of the optical signal after the first channel is altered relative to the second channel. The optical device may include a controller to generate a control signal to adjust a power balance associated with the optical signal based on the optical power measurement. The optical device may include a controller to provide the control signal to a tributary modulator to alter a modulation of the optical signal.

Abstract: In some embodiments, an apparatus includes a quadrature amplitude modulation (QAM) optical modulator which includes a first phase modulator (PM), a second PM, a tunable optical coupler (TOC), and an optical combiner (OC). The TOC is configured to split a light wave at an adjustable power splitting ratio to produce a first split light wave and a second split light wave. The first PM is configured to modulate the first split light wave in response to a first multi-level electrical signal to produce a first modulated light wave. The second PM is configured to modulate the second split light wave in response to a second multi-level electrical signal to produce a second modulated light wave. The OC is then configured to combine the first modulated light wave and the second modulated light wave to generate a QAM optical signal.
