Estimating the term…
The present invention discloses an integrated broadband chaotic semiconductor laser using optical microcavities. The arc-shaped hexagonal laser outputs light. Part of the light is totally reflected through the deformed microcavity and then reflected out of the deformed microcavity from the passive waveguide II; after entering the passive feedback waveguide, another part of the light is fed back into the deformed microcavity by the high reflection film, passes through an in-cavity ray track and then is also reflected out of the deformed microcavity from the passive waveguide II; the two-path light is coupled into the arc-shaped hexagonal laser, and finally generated chaotic laser light is directionally coupled and output through the passive waveguide I at the other end of the arc-shaped hexagonal laser. The present invention has wide broadband, flat spectrum, compact structure, and no time delay signature.
