Experimental demonstration of ultrathin broken-symmetry metasurfaces with controllably sharp resonant response
Odysseas Tsilipakos, Luca Maiolo, Francesco Maita +5
Symmetry-protected resonances can be made to couple with free space by introducing a small degree of geometric asymmetry, leading to controllably-sharp spectral response. Here, we…
Breaking Reciprocity in a non-Hermitian Photonic Coupler with Saturable Absorption
Dimitrios Chatzidimitriou, Alexandros Pitilakis, Traianos Yioultsis +1
We study the breaking of reciprocity in non-Hermitian coupled photonic waveguides by the simultaneous action of the nonlinear effect of saturable absorption, and the presence of ex…
Asymmetric Si-slot Coupler with Nonreciprocal Response Based on Graphene Saturable Absorption
Alexandros Pitilakis, Dimitrios Chatzidimitriou, Traianos V. Yioultsis +1
We present the study of a proof-of-concept integrated device that can be used as a nonlinear broadband isolator. The device is based on the asymmetric loading of a highly-confining…
