| Abstract: | A coupling system composed of two pieces of gradient index rod lenses is developed to achieve optimized coupling between a collimating light beam and a single mode fiber.The calculating expressions for the construction parameters of the coupling system are given,and the digital computing by using computer was carried out,the analytical formula for obtaining the optimized construction parameters were derived.The formula show that the best solution for the coustruction parameters is exist and unique,and is harmonic and symmetric. |
