【Abstract】 Static operation characteristics of an external cavity semiconductor laser with fiber Bragg gratings are simulated by using the rate equations. Relations between its longitudinal mode characteristics and parameters and operating conditions of the device are derived. Single mode operation with side mode suppression ratio more than 40 dB, spectral linewidth nearly 0.1 nm is realized experimentally by coupling an AR coated semiconductor laser with a fiber Bragg gratings fabricated by authors. The experimetnal results are mostly coincident with the simulation.更多还原
