Magneto-Photonic Crystal Isolators  This technology allows for the development and fabrication of an ultra-short optical isolator that can be integrated onto a microchip. Isolators created with this technology could be used in integrated photonic circuits and are smaller and more inexpensive than isolators fabricated by traditional means. |
Frontier Carbon Materials Dr. Yap leads a very focused effort in the atomic bonding control of frontier carbon materials. The majority of his time is specifically spent improving recent innovations in the field such as growing carbon-nitride crystals at 800C and 15 atm. Approximately half of Dr. Yap’s work could be classified as highly theoretical with a 10-15 year discovery horizon and the other half being directed in the general direction of a more near term application (5 year horizon). |
MEMS Center in Wireless Integrated Microsystems A multi-university National Engineering Research Center in Wireless Integrated Microsystems funded by the National Science Foundation gives MTU a strong base for microtechnology research. Among its first projects, the center will design a next generation cochlear implant for which MTU will design and build a |
Magnetic Photonic Crystals Researchers are in the process of developing important materials research solutions that will enable the application of thin film magnetic photonic crystals to high performance electro-optical devices. Of great interest is a process that allows characterization and measurement of properties of novel materials that can simultaneously show piezoelectric properties, and change their index of refraction. These materials are used as [photonic crystals], materials that selectively filter frequencies of light and are tunable with an electric field. |
Integrated Photonics and Materials Integration Laboratory The equipment in the laboratory 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 centered 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.
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; an optical testing laboratory for the analysis of waveguide devices that includes HP and Ando infrared tunable laser sources. |
