Analysis of a High-Speed Kerr-Magneto-Optic Detection Scheme for Crossties.
Abstract
An analysis of an integrated Kerr-magneto-optic modulator based on partially transparent gyroelectric permalloy films is given. This device was originally proposed in conjunction with a readout scheme for crosstie-Bloch line pairs in a crosstie memory. The problem of integrating a wave guide modulator having weakly or strongly absorbing (ferromagnetic) walls in the form of thin gyroelectric films on non-absorbing dielectric substrates, with an isotropic, non-absorbing, dielectric wave guide is analyzed. Computer generated curves are presented, which show the angle of incidence and film thickness dependence of the longitudinal Kerr-reflection coefficient and of the figures of merit for magneto-optic modulation by thin permalloy films sandwiched between different dielectrics.
