Abstract
A method of making a transverse Anderson localization (TAL) element includes mixing pellets together to make a mixture, the pellets being of two or more distinct materials having respective wave speeds effective to provide Anderson guiding. The mixture is fused to make a preform which has respective pellet-size areas of the distinct materials corresponding to the pellets in the mixture. One or more stretching operations is performed to stretch the preform into the TAL element.
Claims15
A method of making a transverse Anderson localization (TAL) element, comprising:
- for a preform, (1) mixing pellets together to make a non-homogeneous pellet mixture including pellets of two or more distinct materials having respective distinct wave speeds effective to provide Anderson guiding in the TAL element, and (2) fusing the pellet mixture to make the preform, the fusing being done in a non-homogenizing way to retain the non-homogeneity of the pellet mixture and to produce the preform having pellet-size areas of the distinct materials corresponding to the pellets in the pellet mixture;
- and
- performing one or more stretching operations to stretch the preform into the TAL element.
