Abstract :
This paper describes a simple methodology implying the use of optical low-coherence reflectometry and its associated simulations to detect and spatially localize defects in Bragg grating based emission devices such as a phase-shifted DFB laser and a DBR laser with an involuntarily introduced defect in the grating
