“…1, where the wavelength ..\ is 1.152/'Lm and the refractive indexes of a substrate and a top layer are n~ = 1.95 and nc = 1.0, respectively. The refractive index no: = n 1l = n z ~ n and the off-diagonal component of the relative permittivity tensor 0 of magnetooptic materials are given in Table I [2], [7], [8], (13]. For simplicity, we assume the artificial boundary walls x = ±X /2, y = -Y~, and y = t + Y c (magnetooptic rib waveguides) or y = t+h +Y c (magnetooptic ridge waveguides) far from the core region.…”

Abstract-A finite-element method based on the scallll"-wa ve approximation is developed for the analysis of magnetooptic waveg uides. A si mple and efficient itentive method is proposed for soh'ing a nonli nea r eige nvalue equation derived from the scalar fi nite-element approach. To show the validity and usefulness of this method, examples are computed for magnetooptic rib-type a nd ridge-type waveguides. Subsequently, we discuss the waveguide structures which have la rger non reciprocal phase shift.

“…31,32 To evaluate this factor, we calculated the influences of the CeYIG optical absorption and Faraday rotation on the device sensing FoM. [22][23][24] The FoM is observed to increase exponentially with decreasing the CeYIG optical loss and increase linearly with increasing the magneto-optical effects of the CeYIG. So the optical loss of the CeYIG is a very important factor for device performance.…”

“…20 A two dimensional (2D) model was used in the simulations. By adopting the material parameters of Ag 21 and CeYIG, [22][23][24] and varying the incident light angle and wavelength, we observed MOSPR at phase matching conditions for SPP excitation.…”

In this paper we present a new magneto-optical surface plasmon resonance (MOSPR) sensor using a dielectric magneto-optical thin film of Ce1Y 2Fe5O12 (CeYIG) and a metallic film of Ag. We demonstrate that by combining the low optical loss of Ag (ε =-62.485+4.331i) and the strong magneto-optical effect of CeYIG (ΦF = 2 × 104 deg/cm) at ∼1000 nm wavelength, a high figure of merit (FoM) for index sensing can be achieved. The device shows a factor of 20 improvement in the index resolution in comparison with ferromagnetic metal based MOSPR sensors at the same wavelength. By carrying out both analytical and numerical simulations, an optimized Ag/CeYIG MOSPR structure with the highest index sensitivity is achieved at the incident light wavelength of 1160 nm and the CeYIG thickness of 25 nm. The enhanced resolution of the DMOSPR sensor has been attributed to both the field enhancement at the sensing interface due to the high index of CeYIG films and, the high magneto-optical figure of merit of the CeYIG near infrared wavelength range.

“…In 1973, the Faraday rotation angle in the VIS and NIR regions of Bi 3+ -doped YIG was found to be one to two orders of magnitude larger than that of pure YIG [16−18] . In 1988, Ce 3+ -doped YIG was investigated and its magnetooptical properties were found to be more efficient than those of Bi:YIG [19] . Previous works have also investigated Tb 3+ -doped Y 3 Al 5 O 12 (YAG) [20,21] .…”

The ion substitution characteristics of Y 3+ -doped (Tb0.8Y0.2)3Al5O12 transparent ceramics synthesized by a solid-state reaction and vacuum sintering are investigated. The sample sintered at 1 680• C exhibits the best optical properties, yielding a transmittance >75% from 900 to 1 600 nm. The Verdet constant of this sample at 632.8 nm is -108.79 rad·T −1 ·m −1 . X-ray diffraction (XRD) results show that all of the samples have a pure garnet crystal structure without secondary phases. The microstructure of the samples reveals homogeneous grain sizes that averages <10 µm.
