The Micron Optics Fiber Fabry-Perot
(FFP) tunable filter is a specialized optical tunable
filter based on Fabry-Perot etalon technology. The FFP tunable
filters passes wavelengths that are equal to integer fractions
of the cavity (etalon) length; all other wavelengths are
attenuated according to the Airy function.
The key to the elegant design of
the FFP tunable filter is the lensless fiber construction.
There are no collimating optics or lenses, thus the FFP
tunable filter achieves high finesse and maintains a low
loss transmission profile. Micron Optics has eliminated
the pitfalls of other Fabry-Perot component technologies,
including misalignment, environmental sensitivity and extraneous
modes.
The all-Fiber FFP tunable filter follows
the Airy function so closely that engineers can design it
into their opto-electronic systems with a high degree of
confidence that it will provide results very close to the
theoretical mathematical model. Low loss, high isolation
and accurate power or wavelength measurements are just a
few of the characteristics resulting from an ideal Airy
function
The FFP-TF2 design provides
improved etalon alignment for stable long-term, high reliability,
and Telcordia-qualified performance at a more attractive
price. Several standard low-cost configurations are readily
available for special uses including sensing, biotech, and
scientific applications. Option available include full-band
tuning from 1260nm to 1620nm along with the largest finesse
range in the industry (from finesse 10 to 16,000). The new
FFP-TF2 is not a direct drop-in replacement for the
original FFP-TF (due to drive voltage and packaging differences),
but these new filters are now more suitable in many volume
applications.

Tunable Channel Drop for Ultra DWDM

Optical Performance Monitoring.
Micron Optics' FFP Technology is the base for the
highest performance optical performance monitor available
today, monitoring up to 400 channels in the C band alone.
The high resolution, deep dynamic range and continuous tuning
combine to allow accurate dense channel analysis. For example,
Micron Optics finesse 10,000 filters have a contrast
factor of 76 dB.
Tunable Optical Noise Filtering
& Channel Locking.
Micron Optics' FFP Technology is used in telecom
systems around the world for optical noise filtering and
dynamic channel locking. A key attribute is the extreme
low loss nature (to < 1.5 dB) of the filter and its reliable
locking capability. Data from thousands of filters in the
field has shown a projected reliability of less than 80
FITs. The resulting benefit is an extremely low bit error
rate and high network receiver sensitivity.
Tunable Channel Drop for Ultra DWDM
(<25 GHz spacing). The rapid tuning and locking capabilities
of Micron Optics' FFP Technology enables reliable
channel selection and dropping applications in dynamic optical
networks. The high degree to which the FFP filters follow
the Airy Function theory allows optical engineers to accurately
design system performance parameters, without the overhead
of allowing for imprecise measurements.
The table below lists standard filters
used for the most common applications. These filters typically
have short lead times. In addition to these standard filters,
Micron Optics will be pleased to produce custom filters.
