“…As the result of our previous PZT-driven MOSLM, a driving current was reduced less than 10 % as compared with that of the conventional MOSLM [1]. Various types of SLMs with pixel arrays have been intensively developed.…”

“…Here, the SGGG is Czochralski-grown single crystal gadolinium gallium garnet with Ca, Mg and Zr substitution. When we applied a voltage to the piezoelectric PZT layer between the upper electrode and bottom one, the PZT layer gives a stress to the Bi:YIG layer according to the equation (1). Figure 1 (a) shows an initial phase of saturated magnetization of the Bi:YIG layer by an external bias field.…”

A magneto-optic spatial light modulator (MOSLM) driven by electric field is presented. Using finite element method simulation, the parameters of the MOSLM are decided including the 1 µm piezoelectric lead zirconate titanate (PZT)-based layer, the 200 nm bottom electrode, and the 8V electrical applied voltage. A flat surface magneto-optical bismuth-substituted iron garnet (Bi:YIG) based film having an array-pixels structure was created by a site-selected epitaxial method on a SGGG-based substrate. In order to avoid high temperature annealing process which may damage the Bi:YIG film, the PZT film was deposited by the aerosol deposition method (ADM) on the Bi:YIG film. By stress field induced by the PZT film to the Bi:YIG film with an external magnetic field, the pixels of the device were successfully switched.

“…This flat surface plays important roles in the fabrication of the MOSLMs because there is no need for a planarization process for depositing conductor lines for physically isolated pixels. [10][11][12][13] To investigate crystallized properties of two garnet films, the magnetic garnet layer was wet-etched in a H 3 PO 4 and H 2 SO 4 solution at 100 C at an etching speed of 100 nm/min for 1 min. Figure 7 shows SEM images of the wet-etched garnet film of Fig.…”

We investigated selective-area micropatterning of iron garnet film grown by liquid-phase epitaxy (LPE). This method of producing a flat-surface structure overcomes the disadvantages of geometrical grooves, which are formed by wet or dry etching, with a limited resolution due to underetching and nonplanar structure. Moreover, patterned iron garnet films grown by selective-area LPE have better single-crystal properties than films grown by selective-area sputter epitaxy deposition. Thus, this method offers new possibilities for the fabrication of integrated magnetooptic light switch arrays, magnetic waveguides and other magnetooptic devices.

“…An intriguing property of the defect modes of magnetic photonic crystals (MPCs) is the enhancement of Faraday rotation (EFR), which shows useful applications for reducing the length of rotation devices [3][4][5]. The EFR was predicted early in onedimensional central defect type MPCs where the centre magnetic layer is thicker than other magnetic layers [6].…”
