Description
The performance of an EDFA
(Erbium Doped Fiber Amplifier) can
be directly affected by the
characteristics of the pump laser
diode. Pump laser specifications are
often adversely affected by
unwanted external reflections
coupling back into the laser cavity,
and by temperature and injection
current fluctuations.
The Alcatel 1998 PSF locks the
emission wavelength of your 980nm
pump laser and provides immunity to
spectral mode hopping due to
changes in temperature, drive
current and optical feedback. Alcatel
Optronics offers 980 pump stabilizer
in singlemode or polarization
maintaining fibers and in different
recoating diameters.
Alcatel Optronics provides a flexible
product and manufacturing
capability, which enables rapid
design to production cycle times.
Through the use of proprietary fiber,
custom-grating designs to meet
specific customer applications are
available on request.
Features
• Standard single-mode or
polarization-maintaining fiber
• Large production capability
Applications
• Improved spectral characteristics of
980nm pump lasers
• Reduced intensity fluctuations
• Improved manufacturing
wavelength tolerances
