Abstract
In recent years, great progress has been made in the field of tunable vertical cavity surface emitting lasers. The vertical cavity surface emitting laser is perpendicular to the substrate, and this novel structure has the advantages, such as small optical divergence angle, being suitable for integration with other optoelectronic devices, and testing in chip. Simulation method was used to simulate wavelength tunable vertical cavity surface-emitting lasers with micro-mechanical structure. The structure, principle and development history of tunable vertical cavity surface emitting lasers were described. The advantages and disadvantages of different structures were introduced. The development prospects of tunable lasers were also discussed. Wavelength tunable lasers of light source can make network construction cost lower. Large range tunable lasers without mode hop can be used for high-resolution laser spectroscopy and laser ranging. This kind of device has good application prospects in optical transmission, optical interconnection and optical parallel information processing.
