Abstract
We propose a long-range magnetoplasmonic waveguide structure, based on cerium-substituted yttrium iron garnets, that is capable of achieving a useful nonreciprocal phase shift within one propagation length. Incorporating this plasmonic geometry into a Mach–Zehnder interferometer allows for the implementation of an efficient, integrable isolator scheme with an insertion loss of 2.51 dB and an extinction ratio of 22.82 dB. With a small footprint of and nanoscale waveguide dimensions, we envision this device to be a key building block in the development of nanoplasmonic integrated circuitry.
