This work presents a technique based on the application of a high birefringent (Hi‐Bi) fiber Bragg grating (FBG) to monitor the optical signal to noise ratio (OSNR) of an optical channel.A Hi‐Bi FBG produces reflection at two different spectral bands depending on the polarization of the incoming signal. The OSNR can be determined by decomposing, for a data channel, the polarized signal information and the depolarized noise. This work gathers the simulation and experimental results for a single channel system continuous wave signal and modulated at 10 Gb s −1 . The results for a multichannel system are also presented. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:6–9, 2013; View this article online at wileyonlinelibrary.com.
