What was once only a research tool of nuclear physicists, the ion accelerator, offers a means of precisely implanting atoms of any desired species. An electric field accelerates ions to energies high enough that the ions penetrate for some distance Into a solid semi¬conductor. The beam is deflected both horizontally and vertically so that it sweeps the target area in a raster pattern similar to that of the electron beam in a television set.
Electrically and optically active defects in laser-annealed silicon chips are detected through electron beam induced current micrographs.
Laser Chip on Dime
Where discrete semiconductor lasers have mirrors formed by cleaving along an atomic plane, UCSB researchers have begun making laser arrays with etched mirrors, so that the light can be coupled into a waveguide. This method offers the potential of constructing sophisticated optical circuits on a wafer.

Electrical and Computer Engineering
At UCSB's Department of Electrical and Computer Engineer¬ing (ECE), students, faculty, and industry are working together to pave the way for the advanced technologies of the future. Internationally recognized faculty members and research programs are combined with laboratory and computational facilities that are among the best in the nation. A distinguished visiting faculty and
a close affiliation with industry keep the department abreast of worldwide technological developments and real-world industry needs.
The Department of Electrical and Computer Engineering began operations in 1961 and has evolved into one of the largest departments on campus. A wide range of undergraduate and grad¬uate studies are offered, including interdisciplinary studies with the Department of Computer Science. Currently there are 18 full-time faculty members and two adjunct faculty members. Most have achieved international recognition in their areas of specialization,
and nine are fellows of the Institute of Electrical and Electronics Engi¬neers. A nationally and internationally recognized fundamental research program, supported by extramural agencies with total funding exceeding one million dollars, is directly coupled with the graduate degree programs, providing a stimulating environment and making possible a large number of Research Assistantships for advanced graduate students.
The four-year undergraduate program is fully accredited by the Accreditation Board of Engineering and Technology (ABET), and
leads to a Bachelor of Science degree. Undergraduate studies begin with a planned program designed to provide a sound back¬ground in the mathematical and physical principles which are basic to modern electrical and computer engineering. The junior year consists largely of required courses designed to provide the necessary breadth for advanced undergraduate study. The senior year consists entirely of electives concentrated in the student's field of specialization. In all of these courses, the integration of theory and practical applications is emphasized, using a combination of classroom teaching and hands-on experience in the department's outstanding laboratory facilities.
Graduate programs leading to either the M.S. or Ph.D. degrees are offered in the following major areas:
Signals and Systems
Graduate studies are closely linked to ongoing research programs and to a mutually supportive relationship between the department and local industries. At both the M.S. and Ph.D. levels, the emphasis is on achieving both breadth of knowledge and in-depth studies
in the student's area of specialization. UCSB provides substantial support for qualified graduate students through fellowships, teaching and research grants, and non-resident tuition waivers.
