Abstract
The static and dynamic characteristics are investigated for an AlGaInAs/InP octagonal resonator microlaser with a side length of 10.8 μm and a 2-μm-wide vertex output waveguide. The scattered light is observed by top-view infrared microscopic image and compared with simulated mode field pattern. Single-mode operation with the side-mode suppression ratio of 42 dB is achieved. Small-signal modulation responses with a 3-dB bandwidth of 15.7 GHz are reached at 287 K, and a clear eye diagram is demonstrated at 15 Gbit/s.
