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…
