MICROSTRUCTURED OPTICAL FIBERS AND MANUFACTURING METHODS THEREOF
First Claim
1. A method for manufacturing an optical device, comprising:
- providing a plurality of first materials M1 having a first set of characteristic properties;
providing a plurality of second materials M2 having a second set of characteristic properties different from the first set;
making first preforms from materials M1 and M2;
drawing the first preforms into a first regular shape to form first unit cells;
providing a plurality of third materials M3 having a third set of characteristic properties;
providing a plurality of forth materials M4 having a fourth set of characteristic properties different from the third set;
making second preforms from materials M3 and M4, said second preforms having an outer shape of the first preforms;
drawing the second preforms into the same regular shape and size as the first unit cells to form second unit cells;
providing a plurality of fifth materials M5 having a fifth set of characteristic properties;
making a tube from M5;
forming a stack having a predetermined arrangement from multiple ones of the first and second unit cells;
inserting the stack into said tube made from M5; and
drawing the stack into a drawn unit that is configured to guide light in at least one region including the material M1.

Abstract
Optical devices and a method for manufacturing these devices. One optical device includes a core region having a first medium of a first refractive index n1, and includes a cladding region exterior to the core region. The cladding region includes a second medium having a second refractive index n2 higher than the first refractive index n1. The cladding region further includes a third medium having a third refractive index n3 lower than the first refractive index n1. The third medium is dispersed in the second medium to form a plurality of microstructures in the cladding region. Another optical device includes a plurality of core regions including at least one core having a doped first medium, and includes a cladding region exterior to the plurality of core regions. The core regions and the cladding region include a phosphate glass.
