Microwave limiters implemented by coupled dielectric resonators based on a topological defect mode and CT-symmetry breaking
Mattis Reisner, Fabrice Mortessagne, Eleana Makri +2
We present a microwave realization of a reflective topological limiter based on an explicit self-induced violation of a charge-conjugation (CT) symmetry. The starting point is a bi…
Asymmetric Acoustic Energy Transport in Non-Hermitian Metamaterials
Ramathasan Thevamaran, Richard Massey Branscomb, Eleana Makri +4
The ability to control and direct acoustic energy is essential for many engineering applications such as vibration and noise control, invisibility cloaking, acoustic sensing, energ…
Unidirectional Photonic Circuit with Phase-Change Fano Resonator
Roney Thomas, Eleana Makri, Tsampikos Kottos +2
We demonstrate that the integration of a phase-change material (PCM) in one of the two microresonators of a photonic metamolecule, coupled to a bus waveguide, can lead to unidirect…
Waveguide photonic limiters based on topologically protected resonant modes
U. Kuhl, F. Mortessagne, E. Makri +2
We propose a concept of chiral photonic limiters utilising topologically protected localised midgap defect states in a photonic waveguide. The chiral symmetry alleviates the effect…
Experimental Realization of a Reflective Optical Limiter
Jarrett H. Vella, John H. Goldsmith, Andrew T. Browning +4
Optical limiters transmit low-intensity light, while blocking laser radiation with excessively high intensity or fluence. A typical passive optical limiter absorbs most of the high…
Hypersensitive Transport in Photonic Crystals with Accidental Spatial Degeneracies
Eleana Makri, Kyle Smith, Andrey Chabanov +2
A localized defect mode in a photonic-layered structure develops nodal points. Placing a thin metallic layer at such a nodal point results in the phenomenon of induced transparency…
Reflective Optical Limiter Based on Resonant Transmission
Eleana Makri, Tsampikos Kottos, Ilya Vitebskiy
Optical limiters transmit low-level radiation while blocking electromagnetic pulses with excessively high energy (energy limiters) or with excessively high peak intensity (power li…
Non-Linear Localized Modes Give Rise to a Reflective Optical Limiter
Eleana Makri, Hamidreza Ramezani, Tsampikos Kottos +1
Optical limiters are designed to transmit low intensity light, while blocking the light with excessively high intensity. A typical passive limiter absorbs excessive electromagnetic…
