Abstract
In the system of the present invention, two DFB laser outputs are combined in a first stage to produce a beat signal. The two main channels interfere with each other to form beat signals. This combined signal is then used as the seed to create multi-channels through optical fiber non-linearity in a multiplier stage.
Claims10
A multi-wavelength laser source (MWLS) system, comprising:
- (a) first and second monochromatic lasers having first (f1) and second (f2) lasing frequencies, respectively;
- (b) means for amplifying combined signals of said first and second lasers;
- (c) means for multiplying the amplified combined signals to yield comblike multi-channel WDM laser signals separated from each other by a frequency equal to the difference between f1 and f2.
