Research Abstract |
We experimentally and numerically investigated various geometries of two-dimensional (2D) microcavity semiconductor lasers. The obtained results are summarized as follows: (i) In fully-chaotic microcavity lasers, stable single-wavelength lasing can be achieved owing to frequency-locking interaction among the lasing modes (ii) A 2D external cavity structure with a long-periodic orbit was designed and fabricated. Fast chaotic output can be generated by controlling the optical feedback caused by the external cavity. (iii) Moreover, we investigated the phase dynamics of lasers driven by optical broadband noise, and we revealed that the noise can induce synchronization in the laser phases.
