“…General treatments as to gyrotropic waveguides have previously been shown by Yamamoto et al [6], [11], Miyazaki et al [12], and Torfeh et al [13]. We here show one approach to the problem of the magnetic garnet waveguides.…”

This paper shows results of analyses about nonreciprocal and reciprocal properties in magnetic garnet films in order to deal with the single section unidirectional mode converter (SSUMC) required for integrated optical waveguide isolators. The analyses are made from a viewpoint of relative permittivity tensors, [K .. ], of anisotropic materials according to the method shown by Yamamoto et al •• The directiofiJof magnetization which gives the maximum effect on reciprocity is shown for each of the K and the K perturbation, respectively. In these two perturbations, it is expected that the reaYprocal eff¥~t obtained from the K perturbation is almost the same amount with the nonreciprocal effect due to the same K pertG¥bation. From the obtained results, a possibility of realization of the SSUMC using Bi-sub~~ituted iron garnet films as a gyrotropic waveguide is .discussed.

“…Once Bi-substituted YIG was discovered to have much higher Faraday rotations than unsubstituted YIG [10], Van Engen et al [11] used these Bi:YIG garnets to obtain 90% mode conversions (again higher order modes) but high fields were required due to a strong out-of-plane magnetic anisotropy. This new anisotropy caused a birefringence that was opposite in sign to the shapebirefringence [12], [13], and Okuda et al found the two could be balanced to obtain 95% TE-TM mode conversion for lower order modes (m 0 , m 1 ). They also found that fine adjustments in shape anisotropy by acid etching could be used to nearly perfectly cancel the shape anisotropy with stressor growth-induced birefringence such that they achieved 80% lower order mode conversion with very low applied fields [14], [15].…”

Integrated Magneto-Optical Materials and Isolators: A Review

Many novel materials and device designs have been proposed as photonic analogs to electrical diodes over the last four decades. This paper seeks to revisit these materials and designs as advanced technologies may enable experimental realization that was not possible upon conception of several of these designs. The background behind integration challenges, including waveguide birefringence, fabrication tolerances, garnet/semiconductor mismatch, and optimized interfaces will hopefully spark new ideas that will finally enable the realization of integrated optical isolators and circulators.

According to the coupled-mode theory of magneto-optic (MO) effects as a perturbation, the coupling equations for optical pulses with microwave magneto-static waves (MSWs) in MO film waveguides are presented, which can be used to analyze MSW-based optical pulse signal processing. For the case of a continuous MSW, the analytic expression for the complex amplitudes of diffracted and undiffracted optical pulses is obtained in frequency domain and then the compression characteristics of linearly chirped Gaussian optical pulses are studied in detail. The peak intensity of diffracted optical pulses is approximately proportional to the matching diffraction efficiency. With the increase of chirp parameters, the diffracted pulse waveforms go through two stages: single peak compression and multi-peak expansion. #
