WebJun 24, 2024 · Numerical analysis of a magneto-optical (MO) fiber based on cerium-substituted yttrium iron garnet (Ce:YIG) is presented to design a kind of MO isolator. The unique MO properties of garnets are used to produce the non-reciprocal (NR) effect. The aim of this work consists of optimizing the properties of the fiber by reducing modal … WebJan 6, 2012 · Based on the results, Feng et al. claim the existence of nonreciprocity in their design and suggest the possibilities of applying the observed effect toward creating on-chip optical isolators. However, one must ask: (i) Is the observed effect of one-way photonic modal conversion truly a proof of optical nonreciprocity?
WebOct 20, 2024 · The electronic drive and lack of magneto-optic materials suggest the potential for straightforward integration with drive circuits, including in monolithic CMOS electronic-photonic platforms, enabling a fully contained 'black box' optical isolator with two optical ports and DC electrical power.
