Abstract:
A Bragg grating writing system for optical networks comprising:an optical signal generator for providing an optical signal capable of being communicated via a fiber optic link element providing a communication channel, said optical signal characterized as having an operating center wavelength associated with said channel; a grating writing source for writing a grating pattern on a portion of said optical fiber link, said grating pattern providing a peaked wavelength selective function including a center wavelength; a wavelength-locked loop servo-control circuit enabling real-time adjustment of said grating pattern being written to said fiber optical link element by said source to thereby mutually align said center wavelength of said peaked wavelength selective function resulting from said grating with said center wavelength of said optical signal, wherein the resulting grating writing pattern enables optical signals to be optimally communicated over said communication channel.
