Abstract

The embodiment of the invention provides an integrated chaotic laser chip and a laser. The laser chip comprises a first laser assembly and a second laser assembly. The first laser assembly and the second laser assembly are integrated chips of a distributed feedback laser DFB and a semiconductor amplifier SOA. Wherein the first laser assembly includes a left side DFB region and a right side SOA region, and the second laser assembly includes a left side SOA region and a right side DFB region; The right end surface of the right SOA region of the first laser assembly is plated with a low reflective film, and the left end surface of the left SOA region of the second laser assembly is plated with a high reflective film; The first laser assembly and the second laser assembly are integrally connected through the low reflective film and the high reflective film. The laser chip has the advantages of simple structure, easy operation, direct optical coupling by using refractive index matching glue, and greatly improving coupling efficiency.

Description

technical field [0001] The embodiments of the present invention relate to the field of lasers, in particular to an integrated chaotic laser chip and a laser. Background technique [0002] As a special form of laser output, chaotic laser has the characteristics of noise-like wide spectrum, inherently concealed and highly applicable. In recent years, with the gradual establishment and improvement of the theoretical system of chaotic lasers, the development and application of chaotic lasers has become a research hotspot. Due to the advantages of small size, low cost, high reliability, easy integration, and direct modulation, semiconductor lasers have become the superior laser devices for chaotic lasers, and are widely used in secure communications, laser ranging, breakpoint detection, and laser coherence length any control etc. As a kind of semiconductor laser, distributed feedback (DFB) laser has built-in Bragg grating, which has the advantages of realizing dynamic single lo...
