Abstract:
1. An optical system, comprising: a transmitter module comprising: a processor configured to: a digital-to-analog converter configured to: a laser configured to output light; a Mach-Zehnder modulator configured to: a filter configured to: where the digital-to-analog converter is a first digital-to-analog converter, the first digital-to-analog converter being configured to: receive a first set of the input values from the processor, and generate the first and second voltage signals based on the first set of input values, the transmitter module further comprising: a second digital-to-analog converter configured to: receive a second set of the input values from the processor, and generate third and fourth voltage signals based on the second set of the input values, where the modulator is a first modulator, the first modulator being configured to: receive a first portion of the light from the laser and the first and second voltage signals from the first digital-to-analog converter, and modulate the first portion of the light based on the first and second voltage signals to produce a first modulated optical signal; the transmitter module further comprising: a second modulator configured to: receive a second portion of the light from the laser and the third and fourth voltage signals from the second digital-to-analog converter, and modulate the second portion of the light based on the third and fourth voltage signals to produce a second modulated optical signal, where the transmitter module further comprises: a combiner configured to: receive the first modulated optical signal and the second modulated optical signal, and combine the first modulated optical signal and the second modulated optical signal to produce the output optical signal, and where the combiner is further configured to reduce or eliminate the distortion from the first modulated optical signal or the second modulated optical signal.
