摘要： Described are an optical transmitter (42) and a method For generating a single sideband optical signal (62). The method includes generating a data signal at a first power level (DS 1 ) and at a second power level (DS2) with a predetermined ratio being defined between the power levels. The data signal at the first power level is applied to a phase module (50) disposed in a laser cavity of a semiconductor laser (46) to generate a frequency modulated laser signal having a double sideband. The intensity of the frequency modulated laser signal is modulated (18) in response to the data signal at the second power level (DS2) to yield the single sideband optical signal (62). Optical transmitters implementing the method have an increased manufacturing yield and reliability, a lower fabrication cost and a decreased size compared to other optical single sideband optical transmitters.
