Manually Tunable Filter and Manually tunable Fiber Grating

(  More than 10nm tuning range )

The manually tunable fiber grating has a wide tunable range, simple structure, high sensitivity, long life time product fabricated with our property technology. The tunable fiber grating can be used as dynamic add/drop, wavelength router/switch, tunable fiber laser, dynamic dispersion compensation fiber grating, dynamic gain flattening, tunable fiber laser, fiber sensor system, biomedical, instrument and other application.

The manually tunable filter is constructed with manually tunable fiber grating and a optical fiber circulator.
