Bandwidth-Variable Tunable Filter <BVF-100>
|
BVF-100 is the latest line of advance tunable optical filters
based on our flexible optical filter tuning technologies. The filter center
wavelength is completely tunable over the entire C-band, and the filter
bandwidth is independently tunable from 0.2nm to 10nm. The filter response
of the BVF-100 is an ideal flat-top profile with a very sharp roll-off
at the filter edges.
The BVF-100 offers a low insertion loss of typically <4dB, and a low polarization sensitivity. More importantly, the BVF-100 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.
