Abstract

In this paper, a new idea is presented to sense the vibrations and temperature using semiconductor optical amplifier (SOA) and Raman amplifier, respectively. The SOA is used because of its compact size, on chip embedability and cost effectiveness. On the other hand, the Raman amplifiers can be used as a distributed amplifier which provides distributed sensing along with the transmission fiber. We have observed the variation of received output power (for SOA -38 to -4 dBm, -44 to -8 dBm, -49 to -13 dBm at different amplifier length such as 100μm, 200μm, 300μm, respectively and for Raman amplifier 15.7 to -40.25dBm, 11.7 to -50.01dBm, 9.1 to -55dBm at different amplifiers length 100km, 200km, 300km, respectively) with respect to the vibrations and temperature..
