K1 Four-wave mixing K1 Semiconductor optical amplifier K1 Standard frequencies K1 Electrónica K1 Electronics AB The generation of standard reference frequencies close to the ITU channels is essential for the calibration and maintenance of DWDM systems. This work describes a method to synthesize frequency references in the range from 187.1 to 205.1 THz (1462-1602 nm). The method is based on the generation of four equispaced frequencies (by the process of four-wave mixing in a semiconductor amplifier) of which two are locked to absorption lines of the acetylene 12C2H2 (1511-1542 nm).
