Research On Laser Emission Technology Which Based On OWDM

With the development of communication technology, the space laser communication becomes a new direction of the optical. communication. The use of the Space laser communication are being more and more extensive. the type of the information which can transput by this technology become more and more. And the information capacity become more large. High channel capacity and high transmission rate are the goals of the tecnology. WDM Provides a good solution.It is researched that the technology of Emission system of the space laser communication and Mades a reasonable system design by researching the fundamentals of WDM and the space laser communication at first. Then it designs a drive circuit for laser and a circuit for temperature controlling.At last, it examines and certifies the feasibility of the system by experiments.
