Optical frequency noise captured as power spectrum density
1/f noise, white noise and lorenzian linewidth analysis
Investigation on ITLA for digital coherent transmission systems
Optional integration with RIN / linewidth measurement functions
SYCATUS provides a new solution of
A0040A Optical noise analyzer for optical
frequency noise measurement. A0040A
enables to investigate the optical frequency noise as power spectrum density.
The spectral purity of laser sources became the most critical concern along with
the evolution of digital coherent transmission method. On the other hand, highly
functional laser sources such as ITLA are
facing the issue of optical frequency uctuations arising from EMI by integration
with electronics or complicated control
scheme.

Laser linewidth measurement is the traditional method for the evaluation of the
spectral purity of laser sources. However,
the laser linewidth is insufcient for the
analysis of the constituent of optical
frequency noise. The spectrum analysis
is mandatory instead of laser linewidth
measurement as DSP in digital coherent
transmission systems has limited bandwidth for frequency offset compensation.
A0040A Optical Noise Analyzer enables to
capture optical frequency noise characteristics as power spectrum density by the
combination of SYCATUS s unique method and Agilent X-series signal analyzer.

Optical Noise Analyzer
A0040A Optical Noise Analyzer is
a powerful tool for investigating
the cause of optical frequency uctuation with the ability of precise
analysis of optical frequency noise
characteristics of laser sources.
A0040A extracts 1/f noise portion
and white noise portion, which enables to derive lorenzian linewidth
composed of only white noise.
A0040A Optical Noise Analyzer
optionally includes RIN measurement function and conventional
laser linewidth measurement function. A0040A improves measurement convenience and investment
efficiency as a totally integrated
noise analysis solution for laser
sources.
