Tunable external cavity semiconductor lasers have excellent characteristics such as wide tuning range, narrow linewidth, high output power, single mode output, etc., which have a wide range of applications in the fields of white light interferometry, wavelength-division multiplexing sys-tems, coherent optical communication, fiber optic sensing and so on. This paper first introduces the basic principle of tunable external cavity semiconductor laser and three main structures of TECDLs are reviewed and compared in detail, such as diffraction grating structure, fiber Bragg grating structure, and waveguide structure. Then describes the domestic and international development status of various tunable external cavity semiconductor lasers, analyzes the advantages and disadvantages of the different external cavity structures, and finally summarizes the shortcomings of tunable external cavity semiconductor lasers, and looks forward to the prospect of tunable external cavity semiconductor lasers development.
