| Abstract: | The optimum design of LiNbO_3 optical transmitter modules in high-speed and broadband optical fiber communication network system is investigated. The advantages and disadvantages of semiconductor laser and LiNbO_3 waveguide laser are compared. The configuration of the two important devices——Er∶LiNbO_3 waveguide laser and LiNbO_3 electro-optic modulator of the optical transmitter modules is designed and studied. The relations of the bandwidth and halfwave voltage of the electro-optic modulator with some key factors are discussed and analyzed. The designed module structure is simulated by BPM software. The transmitting wavelength of this module is 1531nm, the modulating rate is 10Gbits/s. |
