Fiber Bragg Gratings and long period gratings can be constructed using Newport’s Photosensitive Fibers by exposing these fibers to periodic patterns of UV light. Such gratings can form the basis of devices such as wavelength-selective filters, narrow-band mirrors or sensors.
Compared to regular fibers, requiring lengthy UV exposure, the intrinsic photosensitivity of these fibers allows for short UV exposures times without the hassles and potential dangers of hydrogen loading.
A 1 nm-wide, 47 dB deep 15 mm-long transmission grating can be written in these fibers in 10 minutes by a pulsed Excimer Laser (10 Hz, 0.5 J/cm², 248 nm).
Splicing losses to a SMF-28 single-mode telecom fiber are typically less than 0.2 dB.
