Abstract

We design and demonstrate a deformed-square-FP coupled cavity laser that achieves spontaneous chaotic output through the mode coupling between whispering-gallery modes and FP modes. Our lasers are fabricated using i-line projection photolithography, avoiding the need for complex systems or grating fabrication. They have the advantages of a compact size and a simple structure. By connecting waveguide at the vertex of polygonal microcavity, the chaotic output power of microcavity laser is significantly improved, which can reach more than 1mW. The chaotic states can be observed within a current range of 5mA, and its maximum chaotic bandwidth reaches 9GHz. This design provides a new solution for increasing the output power of chaotic microcavity lasers in practical applications.
