Laboratory Facilities

    CEMDAS laboratories, comprising about 18,000 square feet in the Zachry Engineering Center and the Wisenbaker Engineering Research Center at the northeast corner of the Texas A&M campus, are equipped with numerous major capital equipment items for the fabrication, assembly, and testing of electronic, microwave, and electro-optic devices and systems.
 
 

Solid State

   The Solid State Facilities occupy a 7,000-square-foot laboratory that contains a clean room for device processing.  Major capital equipment items include sub-micron-resolution mask aligners, sputtering systems, a dual e-gun deposition system, thermal evaporators, a chemical vapor deposition system, a reactive ion etching system, an ion milling system, plasma etching, wet processing, a darkroom facility with step-and-repeat camera, numerous furnaces and ovens, two laser-trimming systems, a scanning electron microscope, optical microscopes, thin-film thickness monitor, and an ellipsometer.

 

Microwave

 

    The Microwave Facilities include a Hewlett Packard 8510 Automatic Network Analyzer with Synthesized Sweeper operating to 100 GHz, HP 8753 Automatic Network Analyzer operating to 6 GHz, a 40-foot indoor anechoic chamber for antenna pattern measurement from 2 GHz to millimeter wave frequencies,  a rooftop range for UHF antenna measurement, and VAX and SUN workstations with appropriate software for computer-aided-design of microwave circuits and antennas. Other equipment includes sweepers, isolators, tuners, spectrum analyzers, power meters, detectors, slotted lines, directional couplers, switches, attenuators, and waveguides that operate at frequencies to 100 GHz.
 
 

 

Electro-optic

    The Electro-optic Facilities are housed in six labs comprising 5500-square feet. Equipment available for CEMDAS research include Ar, Nd:YAG, Ti:sapphire, and dye lasers; high-speed (20 GHz) semiconductor lasers and photodetectors; a scanning Fabry-Perot interferometer; monochromators; fiber cleavers and splicers; and numerous vibration-isolated tables, micropositioners, and Faraday isolators. Electronic and  microwave equipment includes signal sources and spectrum analyzers to > 25 GHz; a 14 GHz sampling oscilloscope; and numerous analog and digital oscilloscopes, signal generators, power supplies, and lock-in amplifiers. Several personal-computer-based data acquisition and processing systems are also available.
