Paper Abstract

We report the noise and gain characteristics of a 1.3 micrometers PDFFA, in both the small and large signal regime. The small-signal noise performance shows a value of 5 dB at 1.3 micrometers , reducing to < 4 dB for wavelengths < 1.28 micrometers , and increasing to > 7 dB for wavelengths > 1.32 micrometers . No noise penalty has been observed in saturation for output powers as high as + 17 dBm, corresponding to 10 dB gain compression. Crosstalk measurements show a 3 dB rollover frequency of 6 kHz.
