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…
Perfect Impedance-Matched Isolators and Unidirectional Absorbers
J. M. Lee, Z. Lin, H. Ramezani +4
A broad-band reflectionless channel which supports unidirectional wave propagation originating from the interplay between gyrotropic elements and symmetrically placed gain and loss…
Enhanced Transmission and Giant Faraday Effect in Magnetic Metal-Dielectric Photonic Structures
Kyle Smith, Turhan Carroll, Joshua D. Bodyfelt +2
Due to their large electric conductivity, stand-alone metallic films are highly reflective at microwave frequencies. For this reason, it is nearly impossible to observe Faraday rot…
