BVF-200 is the latest line of advance tunable optical filters based on our flexible optical filter tuning technologies. The filter center wavelength is tunable over the entire C-band, and the filter bandwidth is independently tunable from 0.1nm to 13nm. The filter response of the BVF-200 is an ideal flat-top profile with a very sharp roll-off at the filter edges.
The filter features an ultra narrow-band filtering capability down to 0.1nm
with a typical out-of-band suppression in excess of 50dB.
The BVF-200 offers a low insertion loss of typically <4dB,
and a low polarization sensitivity. More importantly, the BVF-200 also
exhibits an extremely low chromatic dispersion within its passband, making
it an ideal and flexible tunable filter for various demanding applications
requiring full tunability in optical filtering.
Bandwidth variable from 0.1nm to 13nm Center wavelength tunning range over
40nm Ideal flat-top filter response with
sharp roll-off Side-mode suppression of >40dB, typically 50dB Low chromatic dispersion within passband <1ps/nm Low insertion loss, low polarization
sensitivity
