Large range wavelength demodulation for ultra-short fiber Bragg gratings based on an arrayed waveguide grating and a convex optimization algorithm
A wavelength demodulation method for ultra-short fiber Bragg grating (US-FBG) sensors based on an arrayed waveguide grating (AWG) and a convex optimization algorithm is proposed and demonstrated. Instead of measuring the output power ratio of the two adjacent AWG channels as previously done, in this...
