In the next generation optical access network, tunable burst laser is one of the key devices. This paper designs the light path for a tunable burst laser based on electric absorption modulated laser and semiconductor optical amplifier. Common optical components are selected by simulation in ZEMAX to improve the light path and the coupling efficiency. The light path consists of electric absorption modulated laser, semiconductor optical amplifier, optical isolator and lens. The minimum launch power that can be calculated by the simulation. The test results show that this design can meet the requirements of the transmitter in the next generation optical access network.
