| Discovery viewed as breakthrough in miniature lasers
The Huntsville Times - November 29, 1993
Northwestern University researchers say they have discovers a way to make high-powered lasers on a computer chip, a breakthrough that should lead to a new generation of miniature lasers. Previously, the only method for producing the lasers on a chip had involved the use of AlGaAs, But the use of aluminum content led to defects in the original construction and sudden failures in operation. ...

| High Powered Laser on a Chip
Inside R&D - October 8, 1993
Researchers at Northwestern University have discovered a way to make high-powered aluminum free lasers on a computer chip. Test on bench versions of he new lasers show them to be more reliable and stable than the best results ever reported for the aluminum-based chips. The lasers should also be simple to produce, easy to operate, and provide a high power density. ... [read more]

| Researcher sheds light on opto-electronics
Chicago Tribune - November 9, 1992
In Evanston, Northwestern University scientist have for the first time built tiny lasers made from exotic materials onto a base of silicon, a difficult technical feat that could advance the marriage of optics and electronics. Razeghi said that the technology she uses to build the tiny laser, a type of chemical vapor deposition is widely used in industry. By teaching students how to use this tool to make lasers of silicon, she said, she is helping industry by providing a skilled work force. ... [read more]
