Abstract :
We report an anomalous phenomenon of output power instability in 980nm LD module with polarisation maintaining fibre (PMF) and fibre Bragg grating (FBG) which is found out at the first time by us. Next, we describe a novel configuration of PMF to eliminate not only the state of polarisation (SOP) fluctuation but also the instability of the output power.
