Abstract

A hollow-core photonic bandgap fiber polarizer may include a core, an inner cladding surrounding the core, the inner cladding including a plurality of capillaries, and an outer cladding at least partially surrounding the inner cladding. A section of the capillaries distal to the core is asymmetric relative to a section of the capillaries proximal to the core.
