Abstract :
Initially, we have inscribed a uniform fiber Bragg grating in a multimode fiber. It was observed that the phase matching condition was approximately satisfied by a few modes, causing the appearance of lateral lobes. We have experimentally analyzed the dependence of these lobes upon variations in temperature. This study may lead to the construction of multimode temperature sensors.
