PHOTONIC CRYSTAL FIBERS WITH HIGH RESISTANCE TO BEND LOSS

摘要

A fiber optic waveguide (30) is disclosed. The fiber optic waveguide includes a core region (34), and a cladding region surrounding the core region. The cladding region includes an inner cladding region (32) and an outer cladding region (38). The inner cladding region has a lattice of large diameter columns (36). The lattice of large diameter columns have a diameter (d) to pitch ( LAMBDA ) ratio defined by the relationship d/ LAMBDA greater than or equal to 0.3.
