Magneto-optic recording

Abstract

With the continued advance in the design and production of small solid state lasers and associated optics, future systems designed to achieve very-high-density storage of digital information are likely to become increasingly dependent on sophisticated optical technology. Non-erasable storage systems that have been accepted for many years (WORM, CD-ROM and so on) show a continuous growth of applications and sales. The first erasable storage systems, produced and marketed to an agreed world standard, are firmly based on magneto-optic recording technology. This review is intended to summarize the systems and materials that have made this technology possible.

The Electronic Structure and Spectroscopy of Metallo‐Dithiolene Complexes

“…Extensive electronic structure and spectroscopic studies of metallo-bis(dithiolenes) have been undertaken as a result of their potential involvement in electrically conducting (115,116,142,145,146,201,202,270,359,(361)(362)(363) and optoelectronic device technologies (113,119,160,248,(364)(365)(366)(367)(368)(369)(370)(371)(372)(373)(374), as well as their presence in the active sites of certain pyranopterin Mo and pyranopterin W enzymes (11, 13, 17, 19, 27, 28, 36, 45- There have been a considerable number of MO calculations performed on four-coordinate square-planar metallo-bis(dithiolene) complexes at various levels of theory (283,327,328,(379)(380)(381)(382)(383)(384). The most important differences in the results of these various calculations rests in the energy level ordering of the valence MOs as well as the degree of metal-sulfur covalency.…”

Advanced Materials and Device Architectures for Magnetooptical Spatial Light Modulators

“…As a result, photon angular momentum and light polarization are slightly shifted due to the MO effects.The spectral and composition dependence of MO effects and their intensities provide characteristic signatures on the electromagnetic (EM) waves or electronic and spin structure of materials. [6] This makes them suitable for various analytical chemical methods such as visible or near-infrared magnetooptical spectroscopy [7][8][9] X-ray magnetic circular dichroism (XMCD) [10][11][12] Brillouin light spectroscopy (BLS) [13] in addition to applications such as optical isolators, [14][15][16] circulators, [17][18][19] spatial light modulators, [20][21][22] polarized microscopy, [23][24][25] sensing/imaging systems, [26][27][28] data storage, [29][30][31][32] and growing field of spintronics. [33][34][35] Among the above-mentioned applications, spatial light modulators (SLMs) have drawn significant attention since they are the key components of many photonic devices including holograms and display systems, optical interconnects, projectors, functional Raman microscopy, and visible light communications.…”
