Abstract

We propose a serialized sensor network using a reflected SOA (RSOA) as a low-cost and wideband source. The RSOA is self-injection locked by the FBG sensors with different center wavelengths. By reading the wavelength shifts, the number of sensors up to 32 can be monitored with the side mode suppression ratio of >27 dB within 4 km.
