Abstract
- Abstract: A novel wavelength-selective all-fiber filter using a single long-period fiber grating (LPG) interacting with a misaligned fusion splicing point has been demonstrated. The misaligned splicing point couples a part of the core mode power into the cladding modes, which is then recoupled into the core mode by the following LPG. As an optical path difference is introduced by the differential refractive index of the fiber, an in-fiber Mach–Zehnder interferometer is therefore formed, which may function as a cost-efficient WDM filter with good isolation and low insertion loss.
