| 英文摘要 | Dynamical characteristics of microcavity lasers are investigated by small signal analysis and large signal simulation based on single-mode rate equations, emphasized on the influence of the mode quality factor (q factor) of the passive cavity and the internal absorption loss. the results indicate that a large 3-db bandwidth does not always accompany a high quality eye diagram, especially for the small signal modulation with a high resonance peak. high q factor and low internal loss are both required for high speed operation at a low biasing current. for a 2.5-mu m-radius microcircular laser with an internal absorption loss alpha(i) = 1 cm(-1) and a cavity q factor of 7 x 10(4), high-quality eye diagrams are realized at a modulation rate of 10 gb/s under a biasing current of twice the threshold current. the results show the broad prospects for the directly modulated microcavity lasers as a low-power efficient light source in on-chip optical interconnection. |
