摘要
An analysis of group-velocity dispersion in graded-index (GRIN) lenses is presented. The analysis shows that continuously adjustable negative group-velocity dispersion up to hundreds of square femtoseconds can be produced by propagating the optical beam off the axis of a GRIN lens. Compared with the well-known prism-pair grating-pair methods for producing negative dispersion, the method described here is advantageous because it is 100-fold smaller, it has low insertion loss, and it is compatible with integrated optics.
