    摘要: A method and system provide for sensing multiple wavelengths simultaneously in a single wavelength sensing device. The system may have a plurality of laser signals and a plurality of identifiable modulation signals. A respective laser signal of the plurality of laser signals is combined with a respective identifiable modulation signal of the plurality of identifiable modulation signals so that each of the laser signals is identifiable. A combined optical signal is then formed from the modulated laser signals. A sensor has an input port that receives the combined optical signal. The sensor identifies, for each of the modulated laser signals, a respective laser signal via the identifiable modulation of the respective modulated laser signal.
