Single-polarization operation in birefringent all-solid hybrid microstructured fiber with additional stress applying parts.
We demonstrate single-polarization (SP) operation in a birefringent all-solid hybrid microstructured fiber that has additional boron-doped stress-applying parts (SAPs). The stress from the SAPs is added to the stress from the highly germanium-doped high-index regions, and SP operation with more than a 25 nm bandwidth was achieved at the shorter wavelength edge of the second bandgap.
