“…The isolators using MO photonic crystals require either precise magnetization domain control over micron scale [8] or complex design of photonic crystals [9]. These issues make them difficult to be experimentally realized.…”

Abstract:A ring isolator is demonstrated for the first time by directly bonding a cerium-substituted yttrium iron garnet (Ce:YIG) onto a silicon ring resonator using oxygen plasma enhanced bonding. The silicon waveguide is 600 nm wide and 295 nm thick with 500-nm-thick Ce:YIG on the top to have reasonable nonreciprocal effect and low optical loss. With a radial magnetic field applied to the ring isolator, it exhibits 9-dB isolation at resonance in the 1550 nm wavelength regime.

“…We find ω ∝ i , and thus is proportional to the magnetization M. To achieve large ω (∼ω 0 i / r ), a magnetic domain engineering is generally needed [25]. To avoid the magnetic domain engineering while still achieving large frequency splitting, one can nevertheless design a more sophisticated resonator and thus using uniform magnetization [26].…”

We propose to create an effective magnetic field for photons in photonic crystal resonator lattices using the magneto-optical effect. The inter-resonator coupling is mediated by magneto-optical waveguides or magnetooptical resonators, and thus the coupling between the nearest-neighbor photonic crystal resonators acquire a direction-dependent phase. The effective magnetic field can be realized with a proper choice of the spatial distribution of such a direction-dependent phase.

“…It was reported that with increasing the amount of Bi substitution for rare-earth element, FR of Bi:RIG becomes large [2]. Bi:RIG have been used for magneto-optical device elements in such as magnetoplasmonic structure [3,4], optical isolators [5], circulators [6], and magnet photonic crystals (MPCs) used in magneto-optic spatial light modulators (MOSLMs) [7]. Among them, bismuth substituted gadolinium iron garnet (Bi:GdIG) is one of the ferrimagnetic rate-earth iron garnets showing perpendicular magnetic anisotropy [8,9].…”
