Wavelength-locked FBG (Fiber Bragg Grating)

Fiber Bragg Gratings have many applications in optical communications, laser technology and sensing systems. FBGs are widely used as fiber reflectors or optical filters with narrowband spectra. FBGs can be used as sensitive elements for strain and temperature measurements.Wavelength Locker FBGs are used as external reflectors for laser diodes. The wavelength generation of pump semiconductor lasers and single frequency lasers is easily stabilized using such fiber gratings. Low reflection gratings with FWHM 0.3 nm – 0.8 nm and reflectivity 2% – 5 % are ideal for pump power laser stabilization. FBGs close to semiconductor laser crystals with FWHM of about 0.1 nm and reflectivity of 10% - 20% are used to create single frequency sources. We present a family of WL FBGs with different accurate wavelength positions up to ± 0.02 nm. The transmission spectrum of the wavelength locked FBGs for laser diode power and wavelength stabilization is shown in the figure.
