Abstract
An optical system includes at least one laser source configured to generate first light having a first spectrum comprising a plurality of first peaks, a waveform generator configured to produce a noise waveform, and an electro-optic phase modulator in optical communication with the at least one laser source and in electrical communication with the waveform generator. The electro-optic phase modulator is configured to receive the first light, to receive the noise waveform, and to respond to the noise waveform by modulating the first light to produce second light having a second spectrum comprising a plurality of second peaks. The peak wavelengths of the second peaks are equal to the peak wavelengths of the first peaks and the linewidths of the second peaks are broader than the linewidths of the corresponding first peaks.
