Mode-cleaning in antisymmetrically modulated non-Hermitian waveguides

Mode-cleaning in antisymmetrically modulated non-Hermitian waveguides

We demonstrate all-optical spatial mode-cleaning in non-Hermitian waveguides. The effect is accounted by a unidirectional coupling among the modes resulting from a simultaneous modulation of the refractive index and the gain/loss along graded index multimodal waveguides. Depending on the spatial del...
