Abstract
By using fiber gratings as pump reflectors with various reflectivities or N pieces of gain fibers with various lengths externally to linear cavity as self-equalizers, a parallel-type, pump-shared linear cavity laser array (LC LA) is proposed and numerically studied, The average output power is increa sed and the maximum power variation among channels is reduced from 7.2 to l ess than 0.1 dB when the reflectivity of each pump reflector or the length of each gain fiber is adjusted appropriately.
