Topological photonics (2018, background): “…are presently being actively explored using either magnetic elements (Bahari et al., 2017; Solnyshkov, Bleu, andMalpuech, 2018), optical nonlinearities (Khanikaev and Alù, 2015; Shi, Yu, and Fan, 2015), or externally modulated elements (Yu and Fan, 2009; Hua et al., 2016; Fang et al., 2017).”
Nonreciprocal Nongyrotropic Magnetless Metasurface (2016, background): “The nonlinear approach involves dependence to signal intensity and severe nonreciprocity-loss tradeoff [33].”
Experimental realization of optomechanically induced non-reciprocity (2016, background): “There are also efforts to create an optical isolator via Kerr-like nonlinearity induced bistability, but the performance for a single-photon-level signal and the isolation from weak backward noise are under debate [17].”
Microresonator Isolators and Circulators Based on the Intrinsic Nonreciprocity of the Kerr Effect (2018, background): “This device works based on asymmetric thermal resonance frequency shifts, with the disadvantage that it would suffer from dynamically reciprocal backwards transmission in the spectral vicinity of the forward transmitted light [22].”
Synthetic dimensions in integrated photonics: From optical isolation to four-dimensional quantum Hall physics (2015, background): “Of these, our setup is most closely related to those with spatiotemporal modulation, which are also perhaps the most feasible schemes for applications as magneto-optical elements can be difficult to integrate on-chip [44], while nonlinear isolators can be limited, for instance, by dynamic reciprocit”
