Detailed Technology Description

Researchers at UCSB have developed a method of fabricating solid state lasers with embedded structures for improved performance via patterning. The patterned layer(s) may be engineered to act as a mirror, optical confinement layer, grating, wavelength selective element, beam shaping element, etc. for the active layers. The primary advantage of this technology is that it provides for fabrication of all the needed functionality in one lithography step via patterning.
