Fiber Bragg grating sensor network based on code division multiple access using a reflective semiconductor optical amplifier

We propose a multiplexed fiber Bragg grating sensor network based on code division multiple access (CDMA) using a self-injection locked reflective semiconductor optical amplifier. The proposed system shows improved scanning time without requiring a tunable laser source or a Fabry-Perot filter. CDMA was used to separate each reflected sensor signal and it shows a high dynamic range of over 40°C and a crosstalk ratio of 27.7:1. © 2009 Wiley Periodicals, Inc.
