Research Faculty Miguel Levy
The equipment in Levy's labs serves the fabrication, testing, and analysis of photonic and piezoelectric structures, materials, and film-based devices. Research in integrated photonics centers on the use of magneto-optic and electro-optic materials. Recent work has focused on the development and fabrication of magnetic photonic crystals. A second thrust involves the development and fabrication of optical and microelectromechanical systems (MEMS) based on novel, highly efficient piezoelectric films.
During the last several years, we have also studied ion implantation-induced defect generation in single-crystal oxides. This work has led to crystal ion-slicing techniques that yield high-quality thin single-crystal ferroelectric films (patent No. 6,120,597). Further research into this technology is also a part of ongoing research.
Tools consist of an RF magnetron sputtering system for the fabrication of magneto-optic films; an electron-beam writing system housed in a JEOL 6400 SEM and a Hitachi Focused Ion Beam (FIB) System for nano-patterning of photonic structures, both housed in the Applied Chemical and Morphological Analysis Laboratory; a metal evaporator for the deposition of electrodes; a micro-manipulator; a prism-coupler for the study of refractive indices and film thickness; and an optical testing laboratory for the analysis of waveguide devices that includes HP and Ando infrared tunable laser sources. In addition, Levy's research also makes use of various other facilities housed in the Minerals and Materials Engineering Building, including an x-ray powder diffractometer and a high-resolution Bede X-ray diffractometer for crystallographic analysis; a Chemically-Assisted Ion Beam Etching (CAIBE) system; and an EVG photolithographic mask-aligner for waveguide and electrode patterning.
