Unidirectional Lasing Emerging from Frozen Light in Non-Reciprocal Cavities
H. Ramezani, S. Kalish, I. Vitebskiy +1
We introduce a class of unidirectional lasing modes associated with the frozen mode regime of non-reciprocal slow-wave structures. Such asymmetric modes can only exist in cavities…
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…
Observation of Asymmetric Transport in Structures with Active Nonlinearities
N. Bender, S. Factor, J. D. Bodyfelt +3
A mechanism for asymmetric transport based on the interplay between the fundamental symmetries of parity (P) and time (T) with nonlinearity is presented. We experimentally demonstr…
