Resonant interaction of slow light solitons and dispersive waves in nonlinear chiral photonic waveguide

Publisher's version (útgefin grein)We study the structure of the elementary excitations and their propagation in chiral hybrid structure, comprising an array of two-level systems (TLSs) coupled to a one-dimensional photonic waveguide. The chirality is achieved via spin-locking effect, which in an ideal case gives perfect unidirectional excitation transport. We show that the application of transverse magnetic field which mixes the corresponding levels in TLS results in the emergence of the slow light mode in the photonic spectrum. Finally, we demonstrate the protocols of writing the signal to the slow light mode as well as reading it out with ultrashort optical pulses, which opens new avenues for the realization of optical memory devices based on chiral optical systems.The authors thank Dr MI Petrov for enlightening discussions.
