[Abstract]:In recent years, semiconductor lasers have played an important role in the field of optical communication, and the performance of semiconductor lasers has been rapidly improved. With the development of WDM wavelength division multiplexing optical transmission system, Based on the hybrid integrated miniaturization external cavity tunable laser has the advantages of simple technology, good signal quality and wide tuning range. Due to its long external cavity and external mode selection devices, the external cavity tunable laser is different from the conventional laser in process encapsulation and modulation characteristics. In this paper, the applications of several kinds of tunable lasers with different external cavities are studied in detail, and the different tuning mechanisms and characteristics are analyzed one by one. The basic theories of semiconductor lasers and external cavity tunable lasers are expounded, and the basic characteristics of external cavity tunable lasers are analyzed. Then, the coupling principle and optical structure of active chip and passive waveguide are studied. A silicon optical lens is designed, and the coupling performance of the lens is analyzed and simulated. Finally, the tunable direct modulation characteristics of the tunable external cavity are studied and analyzed. The influence factors of tunable laser with tunable external cavity are divided into optical delay and electric delay. The influence factors are studied and analyzed theoretically, the tunable laser is developed and tested, and the experimental test platform is built. The effect of the influence factors on the direct-modulation characteristics is tested and analyzed. The research content of this paper has some reference value in the design and packaging design of external cavity tunable laser and the research of direct-tuning application.
