摘要
Beam out of SMF can be treated approximately as Gaussian beam, and the N.A. of SMF is able to be calculated based on the approximation. By ABCD matrix and q parameter its propagation in the Grin lens is analyzed. The couple loss between Gaussian beam and fiber is analyzed by overlapping integral. The approaches to minimize the couple loss through the optimization of design are described. The principle and approach to tune the filter center wavelength by the incident angle of beam are given with tuning formula.
