| 英文摘要 | Electrical and optical coupling in an electroabsorption (ea) modulator integrated with a distributed feedback (dfb) laser have been investigated. the integrated device is treated as a three-port optoelectronic device with two electrical ports and one optical output port. the scattering parameters of this three-port device have been measured in the designed experiment. the measured results indicate that there exists the electrical coupling between the dfb laser and ea modulator of the integrated light source whenever the current applied to the laser section is below or above the threshold current, and the optical coupling will have stronger influence on the frequency responses than the electrical coupling when the bias current is above the threshold. a small-signal equivalent circuit model for the integrated device is established considering both the electrical and internal optical coupling. experiments show that the equivalent circuit model is reasonable and the determined element values are correct. based on the measurement and modeling, the influences of the electrical and optical coupling on the high-frequency responses are investigated and the effective measure to eliminate the additional modulation in the dfb laser are discussed. |
