Normal-law quantile phase filters for mode conversion in single-mode fibers applied to wavelength blockers.
We propose the definition of a new family of complex-amplitude filters. These filters are optimal for mode conversion in single-mode fibers and give rise to a large variety of spatial designs. Among them, we focus on a few that are easy to manufacture and implement, in particular, in an array shape, and present some technical advantages such as tolerance to positioning. In the second part, we discuss their implementations by using various technologies and the effect of some technical constraints on filter shape and phase distribution. Finally, we illustrate their uses in the case of a dynamic wavelength blocker within the frame of wavelength-division-multiplexing network systems.
