Views of the Laboratory

Lapping & Polishing

One of two Logitech lapping and polsihing systems used to mechanically thin laser diodes in preperatiion for cleaving, or to assist in back-thinning of hybridized focal plane arrays for higher performance.

Since its founding in 1991, the Center for Quantum Devices at Northwestern University has evolved from only a mere vision into a concrete world-class research laboratory, with the mission to pursue academic excellence and high-level research in compound semiconductor science and nanotechnology.

The Center for Quantum Devices has put together a comprehensive facility for solid state research. This Includes semiconductor thin film epitaxial growth, material characterization, material processing and device fabrication, thin film deposition, and device packaging and measurement. The facility occupies a total of 8,000 square feet of laboratory and office space. 3,000 square feet of this total are clean room space in Cook Hall, specifically designed by Proffessor Razeghi.

The Center for Quantum Devices has established a proven research track record covering areas such as: high-power quantum cascade lasers, type-II superlattice infrared photodetectors, quantum dot photodetectors, UV and visible lasers, LEDs, photodetectors, and avalance diodes, quantum well infrared photodetectors, uncooled InAsSb photodetectors, InTlAsBiSb detector technology, aluminum-free high power lasers, and antimony based 3 to 5 μm lasers.

For a comprehensive overview of the Center for Quantum Devices and the work currently being conducted here please see this 60 minute video presentation.
