tunable FBG

可调FBG为中心波长/频率可灵活调节的FBG. Tunable Fiber Bragg gratings(tunable FBG) are a valuable option for all applications that require flexibility in center wavelength (and/or frequency).

The tuning setup consists of mechanical assembly where the FBG is applied to. The mechanics induces strain to the FBG, shifting its center wavelength homogenuously and chirp free. The spectral shape of the grating can be specified as for the fixed FBGs.

The tunable FBGs are boxed and they can be equipped with a wide range of connectors. As a special option we offer the devices equipped with switchable adapters， enabling you to clean and/or change your adapters easily.


Tunable FBG有手动调节和软件控制两种版本可供选择。
