Multiwavelength lasers can be generated by adding a Fabry–Perot filter in the ring cavity. Changing the voltage of the piezoelectric transducer (PZT) in the F–P filter, one, two, or three wavelengths can be generated, respectively. The range of the lasing wavelengths is over 7 nm, and the lasing wavelengths are near 1560 nm; the reason is that the EDFA wavelength with the maximum saturation output power is near 1560 nm. © 1998 John Wiley & Sons, Inc.
