“…The Faraday effect of a MO material is usually quantified by the Verdet constant V, which is defined as the rotation of the polarization vector for a linearly polarized light beam under a certain longitudinal (along the light propagation direction) magnetic field (usually 1 Tesla) and 1-m optical path length in the MO material. MO materials with large V and low optical absorption are usually needed for the development of optical isolators and circulators [4,5], which have been extensively used in optical communication systems and laser systems in the near-infrared. In recent years, there is an increasing demand for MO devices operating at the 2 µm wavelength region, which is atmospheric transparent, eye-safe, and low-scattering and distortion for light propagation.…”

“…The analysis may be applied to optimization of magnetooptic waveguides, fiber sensors of currents and magnetic fields, and to the evaluation of magnetic field effects in fiber gyroscopes [39][40][41][42][43]. The approach may be extended to nonreciprocal multilayer and graded circular cylindrical waveguides, nonreciprocal plasmonic waveguides, nonreciprocal cylindrical waveguides of (near) square cross sections [44][45][46][47][48], circular waveguide structures containing cylindrically anisotropic metamaterials [49], and waveguides displaying optical activity [50]. From the analytical point of view, the problem is similar to that of cylindrical quantum potential well with penetrable walls [51].…”

Understanding magnetooptics in cylindrical structures presents interest in the development of magnetic sensor and nonreciprocal devices compatible with optical fibers. The present work studies wave propagation in dielectric circular cylindrical structures characterized by magnetic permeability and electric permittivity tensors at axial magnetization. The Helmholtz equations deduced from the Maxwell equations in transverse circularly polarized representation provide electric and magnetic fields. With the restriction to terms linear in off-diagonal tensor elements, these can be expressed analytically. The results are applied to magnetooptic (MO) circular cylindrical waveguides with a step refractive index profile. The nonreciprocal propagation is illustrated on waveguides with an yttrium iron garnet (YIG) core and a lower refractive index cladding formed by gallium substituted yttrium iron garnet (GaYIG) at the optical communication wavelength. The propagation distance required for the isolator operation is about one hundred micrometers. The approach may be applied to other structures of cylindrical symmetry in the range from microwave to optical frequencies.

“…Conventional dielectric-loaded plasmonic waveguides are ideal for such a task, as they are comprised of a ridge of dielectric set atop a metal slab. One such design employs a dielectric core of Bi:YIG deposited onto an Ag slab [90], illustrated in Figure 8(A). The phase shift in the optical mode could be switched via 100-500 ps current pulses passing through the underlying Ag.…”

Abstract:As modern complementary-metal-oxide-semiconductor (CMOS) circuitry rapidly approaches fundamental speed and bandwidth limitations, optical platforms have become promising candidates to circumvent these limits and facilitate massive increases in computational power. To compete with high density CMOS circuitry, optical technology within the plasmonic regime is desirable, because of the sub-diffraction limited confinement of electromagnetic energy, large optical bandwidth, and ultrafast processing capabilities. As such, nanoplasmonic waveguides act as nanoscale conduits for optical signals, thereby forming the backbone of such a platform. In recent years, significant research interest has developed to uncover the fundamental physics governing phenomena occurring within nanoplasmonic waveguides, and to implement unique optical devices. In doing so, a wide variety of material properties have been exploited. CMOS-compatible materials facilitate passive plasmonic routing devices for directing the confined radiation. Magnetic materials facilitate time-reversal symmetry breaking, aiding in the development of nonreciprocal isolators or modulators. Additionally, strong confinement and enhancement of electric fields within such waveguides require the use of materials with high nonlinear coefficients to achieve increased nonlinear optical phenomenon in a nanoscale footprint. Furthermore, this enhancement and confinement of the fields facilitate the study of strong-field effects within the solid-state environment of the waveguide. Here, we review current stateof-the-art physics and applications of nanoplasmonic waveguides pertaining to passive, magnetoplasmonic, nonlinear, and strong-field devices. Such components are essential elements in integrated optical circuitry, and each fulfill specific roles in truly developing a chip-scale plasmonic computing architecture.
